This is for Everquest 1.
ISXEQ has been down for about a week now since they had a patch.
EQMule did some major updates to the source code, which broke all plugins/extensions. Some of these changes are above my paygrade and dealing with memory. I've tried a few things to "fix" them safely, but so far nothing has worked.
I have posted on the forums for help: http://www.macroquest2.com/phpBB3/viewtopic.php?f=48&t=20069.
I have asked for help in the IRC channel.
I have PM'd him.
I don't have the time to sit here and beat my head against a wall.
Once(if?) things are resolved with the source code, I can continue to build ISXEQ and everything will work fine. Until that time unfortunately ISXEQ is unsupported.
