Hey, 2,8 was out too early thats true! Try to delete the old folders, especially the LOG files manually. He programmed a new system to save all settings and if u want the chatlogs too. I had bad problems with the chatlog. If you want more detailed informations please contact Lookias or Steps and try to post screenshots.
Just try to change ur login window texts and settings, too, if you know how u fixed problems, please post here, too.
Please delete old incompatibel modules too, they caused some problems here, too. For example the easy hosting feature is new, via wormnat 2. Try it with the new rubberds:
