Crashing when entering server after downloading new ui/spell file

[nilbog]

is your \uifiles\default folder backed up? If so, it will work for loading the game to the point you can /loadskin name.

In the event your default folder is corrupted or missing, you *can* use the velious one in its place with nothing else.

Example: make a folder in \uifiles named backup.

-move all the uifiles folders into \uifiles\backup
-make a new folder named default.
-paste the contents of the velious ui into \uifiles\default.

should have no problems logging in until you can replace your default ui (if you wanted to use it again)
