Getting the same thing. ONLY with GW2 also. no problem with anything else on my system that runs at the same time IE Vent, TS3,
started a few days back but only on one toon that was in Lion’s arch. now it seems i have to avoid Lion’s arch or loose a toon there for days unable to log in.
I think I’ve found the problem.
Incompatible registries.
Run CCleaner to clean up your system and registries. CCleaner Download
I did some testing today, and after CCleaner, I’ve stopped crashing with error:7.
Tried this myself along with 1001 other possable tweeks. yet still Code 7 constantly on toons in Lions Arch
not wanting to sound nasty but i am so glad i found out its not just me that is having this problem.
