Thank you Tien, I tried shutting both Multisim and Ultiboard down and restarting them without result. I tried making different parts to see if any of the names i was using might be creating problems. I finally rebooted the PC and the part I was trying to link to the Multisim database, finally linked. I had the same problem with the next part I made and tried rebooting the PC again, but this time it didn't work. Coevally with this problem, I could not see the top[ copper layer in the process of making parts with the wizard (only the silkscreen layer). I deleted the ub_config file and solved that problem, but the MS database link is still a problem. I plan to delete the ms_config file tomorrow to see if that is whats causing the hang up. Apparently something happened in this machine that screwed up the design suite. I'll let you know what happens when I delete the ms_config file if you wish. I welcome any insights you might have. Thanks, T
