The day I bought the Gold Edition OFP I had problems with it. I emailed Codemasters and the response was as follows:
"Dear Customer,
We have just become aware of a new problem. It seems to be restricted to
Operation Flashpoint install CDs in the Gold Edition package only. So far we
have determined that the install goes well but when you select play, you
receive an “illegal operation in ~DF394B.TMP†error message. When the
install CD is replaced with a CD from the original or “non-gold†box, the
game will then work.
This would indicate the files installed to your computer are not a problem.
Rather, it is when the game needs to access the CD that we see the problem.
We are trying to determine a solution as quickly as we can. We are rushing
copies of problem CDs to our labs in the UK and to the facility in the US
where the CDs were made.
We would not recommend returning the CD to the store for a replacement of
another “Gold Edition†package. Based on our tests, this will not solve the
problem. We do not believe this is not a problem restricted to your
individual CD.
We will post something to our Codemasters USA Technical FAQ page as soon as
there is something to communicate. Please let us assure you that we will
“make this right†and thank you for your patience while we sort this out.
Thank you,
John
