Was overaggressive with MacKeeper and managed to delete several applications. Managed to get important apps back from TM. However, still not back to where I was. Had a session with MacKeeper and they said they could not assist anymore. Most of the problems are aggravating rather than incapacitating. For example, now cant mail a pdf from Mail. Can save as pdf but then have to go back to folder etc. Have restored the library folder to no avail. Any suggestions would be appreciated. Plan to get Lion this summer. Will this cure the ills that caused myself?
