If you do have a spare disk, why not trying it out, and see what happens.
This was my idea. My first installations isn't completely messed up, so i would like to keep it safe for a while...
I've just installed a fresh version of the 1004, and tried a restore of the 810.
But it doesn't seem to do much. I select the zip, choose restore, and after a few seconds, i've got 2 menu's on the left. Nothing more.
I don't see any rooms created or so. So i suppose that backup isn't restore like it should be.
It would be a very fast restore as well, the zip is about 75MB big. So a few seconds for the copy/restore/...
Any suggestions?
I'll start the restore once more, and check back in a while (30minutes?)...
Or...
