BTW, our IT guys are using the Lacerte CL Pack Tool to repair the program after any of these data corruption occurrences. There is a CL Pack Tool for each Lacerte year/version. It is a database compaction and re-indexing tool. They generally make a copy of the data file somewhere as a backup before running this tool (just in case). The tool seems to work pretty well and our own file backups are not usually necessary when using this. We have also enabled server shadow copies on our network for additional backup protection.
