Hi devilwoman85, What version(s) of java do you have installed listed under your program manager in the control panel?
Have you tried installing the
32bit version of Minion? I have recently found some 64bit systems forcing java into 32bit mode.
Also we have found a problem with JUnique (this prevents Minion from loading multiple times) on some system however your symptoms don't match this issue 100% it may be worth a shot. If the 32bit client doesn't work can you try this
alpha release?
