İ played the game and completed chapter2. now i cant move on to area 5004 because my cd has a problem. i need file: AR5004.bif
it says: can't read file: data4.cab
pls can you send it to me? i hope if it will work.
thnx

Try cleaning your CD with a soft cloth.

i have cleaned the cd and the lens but it didn't solve the problem. my cd-rom reader just can't read it. and this makes me sick. if i could have AR5004.bif ...

Your cd drive may very well be going out.

Bis is notorious about not putting an intense amount of copy protection on their games. They do a disk check, and that is about it. No Safedisk 2.6xx junk, that causes all kinds of havoc with generic drives. So, it's not the copy protection that's fuzzing up your cdrom drive. And if the disk is clean, and the reflective layer is still intact, you might have a seeking mechanism going out.

But it might just be the reflective layer in that one part that's causing problems...

is your cd scratched? or has the writing on the top of the cd been scratched or removed? if so, then that cd is scroowed.

Maybe try reinstalling it. I'm no computer expert, but I know that this often helps.

thnx. at last i could run the game. no i am on chpt 4 and im am happy... hope my cd won't create any other problem..

I need help with my game, when I try to go out of the Stone-Gates(a little after the fellwoods, it's the place with the barbarians and moving rocks) to the next area it says:
An Assertion failed in ChDatatypes.cpp at line 261
Programmer says: Uncompression Error: -5
I already tried removing all my party members, cleaning the cd and reinstalled 4 times but ever happens the same thing.My characters aren't hacked and i couldn't find
ChDatatypes.cpp on my computer or in the CDs.I apreciate any help you could give me.Thanks. :eek: :(
Ps:I have the most recent patch

I can't help you, but inform you.

ChDatatypes.cpp is C language source code file. Assertion is a check point, where a programmer check an logical expression.

If this check fails, assertion (is usual implementations) inform about assertion: where it happened (in the source codes) and what it was (it prints the expression or other info).

You cannot find this file, because it is a source file of IWDII. Don't try to find such file. You would be no able to recompile the game.


An assertion can be produced by some unexpected situations in a software. For example if a programmer check if one item does not collide with other item. Imagine a problem with two bouncing balls - if program runs correctly the will never occupy the same place. They can collide only with surfaces. Then they bounce away. But if there is an error in collision routines, an assertion that check objects collision (same space occupation) would fail.

Sometimes it is triggered by unpredicted "inputs" or begin conditions.

If a monster should appear in some place and this place was occupied by your character (teleportation frag in quake :) ) maybe this monster was "moved a little" to not interfere with your character and was placed "in the wall". In some time the game checks if all monsters died. But this one did not. Worse. It's assertion "do you interfere with something" failed - in interferes with a wall. This is bad luck.


Try to load some older saves and play the part again. The begin of a chapter should be fine - everything should start at good beginning conditions.

I wish you good luck with this issue.

P.S. there could be many other reasons for an assertion. Problems with HW drivers, too many software instalation and deinstalations (messed up OS), ...

Thanks.I really apreciate your help.Whenever you need a favor, ask me, I'm in great debt with you.
