exchange server.. help plz?!

[Temil]

I'm currently using TyeJae Night Steel 3.3 by Aeeolag .. and have 2 char's on the new enchange server. When I try to goto the enchange interface, from the mailbox, it only seems to load up a black screen. Probly a simple fix for this, but I dont know what it is. Can anyone help, because changing back and forth from the default, and custom UI is geting anoying =) thanks!
