database error - please help

[tinkerbell]

Normally I am careful with trying to install add ons etc however I tried to install a chatbox which didnt work out exactly so i removed it again. The main problem with this is it was a couple of weeks ago and I hadnt realised it had left any thing behind.

Today after getting a couple of new members (very important as my membership is only at 30 lol) I tried to alter the PM settings for the registered users usergroup and to my horror I get this error displayed

Database error in vBulletin 3.6.8:

Invalid SQL:
UPDATE usergroup SET

Can anyone tell me what this means or how to correct it?

If not can I import an sql query over the top of my database with an older database or would it rewrite all data not just the matching data?

Any help at all that doesnt involve me losing todays new members and posts lol.

If everything fails I can restore to an earlier time but really dont want to have to do that if possible.

Thank you for any help at all.
