I just got a new computer same issues, but if I go to the eBay site compatibility come up not a problem. So eBay is working fine just not working in sixbit. I have been on the road alot so it hasn’t been a big deal, but I am done with shows until next June so I have plenty of time to list items and this is a pain in the butt. I plan to try another listing program for their free trail and see if it is the same if it works fine I will be switching listing programs as it is tough to add new items when it take 30 minutes to get compatibility chart loaded in sixbit not looking forward to listing a part that fits a ton of vehicles!
