ok. First I got the XML isn't loading upon zoning crap. Then I got the "crash to desktop when you enter game or try to zone with UI" crap.
This is the only thing I did.
I put the EQUI and latest Raid window stuff in my CUSTOM folder.
I then opened my XML File and added these two lines to the end of the area where INCLUDES are, since it was not there.
<Include>EQUI_RaidWindow.xml</Include>
<Include>EQUI_RaidOptionsWindow.xml</Include>
NOTE: I DID NOT DELETE ANYTHING ELSE. I simply added these two lines and I have not had either problem happen to me again.
Make sure when you are adding this line you do it before /caption.
Thank you and good luck.
