ok i bought fallout new vegas from eb games today and i cant install it, when i enter the product code it says "invalid product code". i have checked the code 10 times over and i can safely say that it was not missspelt. so can anyone shed some light on what is wrong and what i can do to fix it? thanks in advance.

Try to get someone else to type the code in for you (not trying to be silly) to see if they get the same result, if that doesn't work try contacting customer support from Bethesda.

I spent hours literally hours on a different game because their CD-KEY had an I and it was really an L. Drove me nucking futs until i just systematically tried everything that looked like it.

Glad to hear it finally worked.
