Hy guys, I have succesfully installed parells 3.0 on my imac which is running tiger. I have only once however managed to open it, all other times it bounces my icon and then says cannot open application (or a message of similiar sorts). I have applied all common logic and attempted uninstalling and reinstalling but all to no avail, the problem is still apparent. Does anybody know how to solve this? I spent £50.00 on this from the Apple store, so i would like it sorting. Thanks people!
