Loading char freezing

[NOVA-5]

Since this mornings server restart, i'm having problems loading chars in,
when loading a char it freezes on the loading screen with no option of alt tabbing out
to quit the process & having to pull the plug on my PC.
I've managed to get logged in three time out of 15 tries but when switching accounts to
log another char, same thing happens.
I suspect it's the launcher causing this so wondered if there's any of the setting i could
change that would help or any idea what could be causing it?
