I have cleared out my PMs but I still get an error message when trying to send a new message. It says something along the lines of "you have reached your quota and much clear space before proceeding". Any help?
Hm. Try logging out and logging back in. You are only showing one PM so the system knows you don't have a full PM box, and PMs are enabled for you. Very odd.
Ok. As of today, I think, TD has made changes that affect all users. You need to "purchase" PM space in vbShop, using credits. Or you have to delete every PM both inbox and sent, because the quota is like 5 PMs otherwise.
