After the latest uprade each time I run Parallels it says I must register my copy. I hae a key from Parallels customer service but when I go to register, I am told this copy is already registered. Following various threads in this forum, I went to Terminal on the mac and entered cat /Library/Parallels/.paralells_license_3.0 and I get the message "no such file" I tried cd/Library/Parallels/command ..and got the same no such file entry. Maybe this is why my copy wants to be registered? I am not sure what to do now. After many upgrades I never had trouble before this latest (3.0) upgrade must have erased the license file. Suggestions wouldbe appreciated.
