Slow disk error message in 2.2.1 - even with SSD

hi, I've been using Mainstage 2 since September 2011 and really enthousiastic on the concept. However, with version 2.1 I had a lot of bugs. The main bug was hanging notes and that is really frustrating when you are performing...

anyway, i now upgraded to 2.2 which seems to have solved this issue but now i have a different problem. regularly MS comes with a slow disk error which could be caused by underperforming disks or freefall motion sensor. Well, because of that I upgraded to SSD and spend almost 300 euro's to have this fixed. after replacement I had a extremely fast notebook and thought all issues were over but I still get the errors! when the errors ossurs some sounds get removed from the output which is annoying...

if anyone can help me with this?
