Hi, that error means the data file got corrupted, is it possible your computer was shut off when CoinManage was running?
anyways, if you have MICROSOFT ACCESS you can usually fix the file simply by opening the COINDESC.MDB file mentioned in the error.
If not, we can do it here. Please either ZIP and email the COINDESC.MDB file to: techsupport@libertystreet.com or upload it using a free www.dropbox.com account.
