Dark Messiah M&M Help, installing

[clayh1031]

I have the game and when installing it stops right near the end and says transfer error data3.cab, i tried to put all files from the disk on my desktop so i could make a new disk and it wont let me put the data 3 or 4 files from disk because it says it cant read or error reading, if anyone has these two rar files so i can actually play my game, i would be greatful, i can take pic to show you i do have the disk and box and directions that it came with. I have played on my other pc, i think that a a scratch is preventing me from installing and tried fixing by fixing the scratch but still wont work, please help, thanks again in advance...
