Apparently an unresolved issue remains from the 2005 Beta. That is, I've merged all of the custom DAT files and that worked OK. But when I go to edit the modules, the symbol file names shown are not the ones I've used. (PLC Database File Editor>Settings). Looking in the MDB file itself the names are correctly shown, and therefore the modules insert correctly. Any ides from Jarred, Steve, Nate, or anyone else will be appreciated. Thanks.
