Hey guys, i don't know if any of you have the same problem with me. But i'm having difficulties installing the Enchanced Edition.Firstly, everything goes well at first, until the installation pauses for a while and and error message shows up that shows DATA ERROR ( CYCLIC REDUNDANCY CHECK) with file Data4.cab. This happened at about 60% of the installation.Fine, i tried it again, this time it stopped at about 3% of the installation process showing the same error DATA ERROR( CYCLIC REDUNDANCY CHECK) with another file name. Did it a third time, this time i managed to finish installing the game disc but after i was promted to put in the Bonus disc to finish processing the rest of the installation, the same ERROR pops up, DATA ERROR( CYCLIC REDUNDANCY CHECK) with data5.cab.My point is that my installation is always interrupted at different points of the installation. I did my research, figured out that it might be a faulty disc, so i took the disc back to the retail shop to get an exchange. I explained the shopkeeper my problem and he decided that he needs to test out the disc to make sure it was really faulty. he installed it on his computer in his shop and IT WAS INSTALLED SUCCESSFULLY, TWICE!!! when it didnt work on my com.I'm using a Windows Vista 32 bit Quad Core Q6600 @ 2.4ghz, 3gig RAM, Graphics card 8800GTX, seems to fit the minimum requirement pretty well.The shopkeeper told me it could be my DVD-ROM and not the disc, i'm pretty confused. anybody has this problem? Please help me, i don't wanna waste 52 bucks on this game......
