Consider letting us know a bit more exactly what you are trying to do with some examples of where your attempts are not working, any error messages you are encountering, etc.
Tip: How To Ask Questions To Get Good Answers
The problem continued after upgrading and when I phoned Reckon Support, they told me to go on to this forum to see if someone else could help me! I have also tried to find version 2012/2013 but can not find anything on the Reckon site, so that I am able to upgrade my file to 2012/2013 and this will then allow me to upgrade to 2013/2014. Restoring a backup does not eliminate this problem.
If you have already looked at your backups and they are experiencing the same problem then have you tried opening the sample company file to see if it too is affected.
If it is then this narrows down the problem to the installed software and not just the data files.
If the sample company is not affected by the reports problem, then the problem is isolated only to your data files.
