Sky X not opening

Hello, hoping you can help me

I purchased the sky x pro about a week ago  (love the software by the way)

it was working fine for a few days but now when i try to open it i get the message "the sky x quit unexpectedly"

all my other apps are working fine

I have a mac with OS X 10.6.8 

have tried repairing disk and disk permissions, reinstalling,  and running in safe mode

any advice would be much aprecieated

many thanks
