Possible ramification, or something else? I only installed SS & LM, re-installed PU18, re-registered (no re-install) of DSD's Mag Media. When client tries to run the 941, it errors out with a ""Failed to Open Rowset"" message. When I open the report in Crystal and do a Verify Database, I get a Map Fields window, which shows an unmapped field labeled ""TaxDueOnUnreportedTips"", for which there is no corresponding field to map to. This field is not part of the 4.3 file layout for PR_33, so I can't figure out how it got there. I also re-installed PR-3038 (the 941 update for 2012). Scratching head. Ideas?
