I opened a design table to insert a new config, then my hand accidentaly slipped off the keyboard and engaged a macro that is not used in the design table. All the instances of the config still work in the assemblies, but i cant add any new ones. When i try i get the message "No valid design table instances found". I read that i could delete the table, and that all the configuration would still be there. Would it then be possible to simply insert a new design table and all the instances would then be inserted?? I am worried about wiping out all the configurations that are there, there a literaly hundreds. I've spent the last two hours trying to figure this out, and unfortunately my limited knowledge of excell is showing. HELP!!!AHHH!!
