Hi,
I recently re-installed Windows XP Pro and the first game I installed was Lugaru (mostly because I wanted to test OpenGL and EA's Battlefield games, the only other games I play in Windows, are huge).
After testing OpenGL with a couple rounds of Lugaru, I went on and installed more stuff and forgot to enter my registration key.
So, I'm playing campain mode just now on Insane difficulty and I get the registration required to continue screen. No biggie, just find my key and enter it...
But after I entered the key, my progress has been erased!
How frustrating!
Though it's too late for me, this should be fixed for others.
