Heroes VII

The closed beta has been extended until September 7th.

That's good... I had already resigned myself to the fact that yesterday the beta started to freeze completely when loading a saved game (any game, not just the most recent one), and I didn't want to reinstall it (in case it helps) just for the one day remaining.
For those who are tech-savvy, could you tell me if it's possible to copy the saved game file from somewhere before uninstalling the game, and then paste it into the corresponding folder of the reinstalled game? :)
