hmmm... you should be able to upgrade straight to threads if you have the old upgrade file (not sure if it's still available - check www.ubbcentral.com/downloads .

Otherwise, upgrade to classic 6.7.3 then to threads 6.5.3, following the instructions for both. If your member's area subscription has lapsed you'll probably need to purchase the one for .classic and then transfer it to threads ( I think that's possible <img src="https://www.ubbcentral.com/boards/images/graemlins/smile.gif" alt="" /> ).

If you would like someone to do it for you, groupee does a good job, contact them. I can do it as well if you like, I've done a good number of them over the years. <img src="https://www.ubbcentral.com/boards/images/graemlins/smile.gif" alt="" />
