Hi, I'm not sure if we have already fixed this by remote control, in situations like this we almost always find the older COINDESC.MDB in another folder on the user's hard drive.\
Try opening your Windows explorer, click on your C: drive, then type COINDESC.MDB into the find box at the upper right.
If you find an older COINDESC.MDB file that looks like it could be your old data file:
RUN CoinManage
Select the OPEN COINMANAGE FILE... command and choose the data file you think may be your old file.\
If you have problems, we can remote to your machine and do it from here.
