I loaded it on multiple characters just now with different options and all was well...I did my ranger with your buff and spell windows and my monk with all my usual stuff and ever tried some of the older stuff like the original spell bar and cant create an issue...
Are you doing a clean install or are you using some stuff from a previous install or copy over an older install? The uploads I do assume you start from scratch and just unzip then move the stuff you like. That's why I said if there is something that you like, go to the bottom where it says manage attachments and add it to a post and I can keep it maintained for you...
Sorry, but I can't recreate the problem. Look at your ..\everquest\uierrors.txt file post what the errors are.
