Yeah, I had issues getting past the Venture Explorer intro bit as well. From my experience, just took a few tries, haven’t had issues since.
That is, unless you are experiencing issues after leaving the Venture Explorer, and then trying to go back to it? In which case, somebody more technically informed on the subject than me will probably need to help.
Also, it ain’t my job to moderate here, but there is a sub forum in General Discussion for Egmo’s server, called “LEGO Universe Reborn” right above the suggestions sub forum. You can post this sorta stuff there for future reference.
