Return of Reckoning

This has only started happening since yesterday when I began to level a new character on order; either I join an SC or I fly to another zone my game has maybe a 50% chance to disconnect and put me on the log in screen and I have to restart the client to get back into the game - but when I log in I'm placed at my rally point as though the game thought I was stuck and it did the /stuck command.

I've tried a fresh reinstall of the game, it's on 64 bit and I've tried the audio.myp file. The only thing I can think of is that I recall some issues with being in a guild causing some crashes?

Almost everytime I fly to altdorf I get a loading screen for about 20 seconds then I'm booted out to the character select screen.

Have you tried to turn off effects in video menu? To me those sound like loading textures issues.
