Is this campaign that is crashing a User Campaign, or a regular WW2 LC, or a generated campaign?.

If It is a user campaign, it may have a bad link to the next scenario. I'd need more info if that was the case - which scenario you are playing in the user campaign, and if possible a save game to debug. If it is not a stock User Campaign, ie one we issue then you would need to talk to the original poster though.

And if the crash is thought to be from OOBs you modified - the simple fix is to goto the default OOBs folder under the OOB folder. Just copy those files to the OOB folder to get back to the defaults, if you haven't modified those. (your campaign will be toast if you used the modified units in it of course).

If you really want to deinstall and reinstall, then the easiest way is simply to Go to the windows menu for the game and select the uninstall option Or simply delete the game folder from where you installed it.
Then you will need to reinstall the game and patches from fresh.
