I had to re-Install Vista ultimate on my computer, and when i went to re-install WR2, now iam getting the "Load Operation Error", Its 1.4.3. and starforce patch installed, i was successfully able to select cars, and track, but when i goto begin race the error message came up...and clues?

Any addons involved (the most popular cause of those load errors)? Did you choose a default car and a Synetic track when the error occured? WR2 should be tested with a clean "vanilla" installation, no addon cars or third party tracks. Remove them if possible.

If the problem persists this could be a general error due to the fresh installation. Graphics card drivers were also updated, I guess? Have you tried WR2 using the old drivers on your new system? The latest gfx drivers are not necessarily the best choice for an older game ...

Another popular cause is that WR2 stores savegames in its installation folder. And if that is the default one (in "C:\Program Files\...") it will be dynamically rerouted to another directory by vista, which is likely to cause problems with finding certain files. The solution to that problem is installing WR2 in a non-managed directory like f.e. "D:\Games\WR2".
