I downloaded the latest version back in April of this year. I was upgrading from (I think) the 2014 version. There were problems with some of the files at the time but I thought they were all very old investments that were sold long ago and had not had any activity and I didn't worry about it. I now realized that some investments with holdings were part of this. In total there were about 40 investments that couldn't be opened by the latest version.
I tried to do a restore but I can't access the restores created with the older version of fund manager.
I can't understand how 40 investment files would have suddenly been corrupted, coincidentally the same day I upgraded FM. 81 investment files came across just fine. I have managed to rebuild the most critical file.
I realize this all happened three months ago. Suggestions?
