Keep getting this error

Whenever I start up WDSC I keep getting an error when I try to connect to 
our AS/400 via remote systems explorer.
I'm on version:
Version:
WebSphere Development Studio Client for iSeries

Version: 5.1.2.5
Build id: 20050622_0933

Error is:

java.lang.reflect.InvocationTargetException

I've ignored it a few times, but it just won't go away... :)
