Hey does anyone know what this error could possible mean? I get the same problem with the DLC disc not working at all gonna try it in Safe mode but was wondering if this was the same error people got (its 64 bit Windows 7 is that compaitable with the dlc?)

I do love Fallout 3 and everything but no offense but I think you guys should double check your discs before you sell them hope it isnt just pc neglect due to heavy console support these days.

Thanks to any help though and I do love Fallout 3 completely along with fallout 1-2. Looking forward to Fallout Vegas but will that still have this problem??
