I'm running 6.7.2 Classic version. I'm not quite sure without installing your version under a test run to see what exactly you have in your control panel at this point.
If I get a chance this week I will do just that to see what I can do to help you.
Wow! That would be very generous of you!
I'm considering the fact that the forum's owner (it's attached to a business) paid a good chunk of change to a computer tech who, in the end, didn't really accomplish anything. (the tech did do other stuff for the business but didn't do beans for the forum) Heck if you're willing to have a look for free that'd be great!
If you're willing to help i'll let u know that, at this point, i might consider asking the owner to upgrade if
1 the cost is reasonable
2 the upgrade could be completed by a volunteer like myself without hiring a tech
3 there would not be any risk in having the entire forum crash if someone like myself attempted the upgrage in a DIY style
Again, i thank you for taking an interest in our situation!

(it appears as though the previous 'upgrade' to our forum was more of a 'bridge' to another expensive software that was a costly flop (i was not involved, i don't really know). if there are less costly alternatives i might suggest them (while also suggesting that forum members like myself chip in))
