I'm having mega problems with sonic stage. I recorded several on-line lectures onto my minidisc player and then back on to the computer. This messed up my windows media player (which disappeared a couple times). Then I started to have more and more frequent blue screen crashes when attempting to boot on and found that several times it was related to sonic stage extensions. I cleaned up the computer with pitstop and removed sonic stage. Now when I want to put sonic stage back on, pitstop absolutely will not allow it. I don't know if I should remove pitstop and put sonic stage back on....Every diagnostic I've run says the computer itself is fine. I hate to lose all my sonic stage files. I am especially fond of minidisc players, but I really like using the computer to make cds from my recordings....
