I'm having the same problem. It was working an hour ago but now I can't get into Node Manager with the same message "Cannot use this content" whenever I pressed "Start". I tried switching characters, I tried logging off and on again, still can't get in.
heya, same problem here server velia, trying to log on - log off, and switch characters ... nothing works
still get the message ''you cannot use this content''.
Here is a screenshot. My node manage has gone for the summer :)
To be exact, this happened after reset - Before that, there was no issue.
