I have been using Quicken since 1991. Currently I am using Quicken 2015. This month my checking account entries are disappearing. On a few occasions as I am working with the file the program just shuts down. I keep entering, logging out of the program and poof - they are not there. Created a back file, opened it and still nothing. I have run Validation. I then decided this would be good time to move to Mac. Converting the file results in the lost entries miraculously showing. However, the investment accounts are messed up in terms of holding and balance.. I don't want to re create the file - as i said it goes back ton 1991. I am fine with converting to Mac, but don't want 5 digit errors in accounts. Suggestions?
