Can't connect since update

All of a sudden I can't seem to connect to Guildwars after the update on 7/10. My husband and I are both playing Guildwars and he has no problem to connect. We are using the same router and were prevouisly playing without any problems. But since yesterday I get the error code 007 and can't connect. I've got no firewall activated and I've run my anti-virus program, and there was no virus or spam on my pc. My husband can log in with my password on his pc and then everything is fine. But no luck on mine. Any idea what could be wrong. Since I've played before the update without any problems.
