I am having problems with my mugen on vista that i have never had on XP. First i had the standard Xp sp2. Now i have vista home premium. The problem that i am having is that when i start my mugen on vista it doesnt load and says there is an unknown problem. The funny thing is if i was to take some of my characters out of the char folder and start mugen it runs with no problems. I can then add a little more and restart mugen and it will load all of them. I repeatedly do this until all my characters are loaded. But if i leave mugen alone for a while or restart my computer i have to do the character thing all over again. Can anyone help with this problem?
