Problem with Gaim

I upgraded my Gaim to 1.0.0 the other day (from the one that came with Slackware 10... I think 0.8). And if I just luanch it normally (out of the menu or off the desktop), it comes up with just the login/password area with no GIAM pic or anything. Then, when I try to login, it says "Missing protocol plugin for *screen name*" But it works fine if I launch it as root from a terminal. How can I fix this?
