I think i found the problem... if someone has it i think this might solve it...
Story goes like this.. i work with a PC not a MAC.
(BEFORE) My motherboard is the ASUS P6T Deluxe and because i have plenty of external hardware like printrers scanners ETC , i had to connect MBOX 2 into the extra USB port that i connected in the motherboard.
few days ago, i connected my home amp with SPDIF from the Mbox Card but i noticed that the sound had a problem with playback, moments later i had some crashes and bluescreens every time i was opening, PT8 and FL Studio Soundbooth ETC...
(AFTER) I Connected the Mbox 2 into a RED USB 2 that according to the manual gives even more power, and after that this problem is solved.
The MBOX was under voltage and that was causing windows to stop critical services and cause bluescreen and the usual windows Vista Symptoms...
Know i work Happyly ever after
