Sage 100

Converting from 4.1 to 2014 Advanced 5.10.3 getting an error 121. When I look at the log file, the last thing listed mentions Qty in Shipping which they do not have activated. I converted them about a month ago and now we were hoping to go live. The only thing I did in their 4.1 version after the last conversion was to delete IM transaction history through 9/30/2013. Is that what's hosing this up? Their last conversion took over five hours and they don't really use IM as intended, only to allow invoicing through SO (all imported).

Line 3384 is trying to open the IM_ItemWarehouse file. Invalid program format sounds like a corrupt program, either SO_LevelConversion.m4p (SO folder) or SY_LevelConversionCommon.pvc and SY_Password.pvc in the SY folder.

Thanks @LeeGraham . I recopied ALL the data from 4.1 and it has been converting now for several hours. I didn't remigrate it, just copied it last Friday as well but something may not have copied well. Seems to be good now.
