I just upgrade to Parallels 8 from the 6 two days ago. After installing the 8 it work perfect. Today, the second time I open Parallels 8 from the day of the upgrade, it does not want to start. It opens a small window with the following message: Unable to start Parallels Services Problem ID: 15381 You click OK on the window and the application close. Can someone explain whats happening or how to fix it? Why are so many complaints from Parallels 8 in this Forums? Thanks.
