Permanent crashes

[Tukan]

I'm writing on behalf of my clanmate now. His problem occurs while flying in Aerial Transformation on Gracia. After a certain point on the map, he gets crash and won't be able to log back due to consecutive errors. Some people have already logged in with his account, they had no problem.

Additional things: still 40GB free space left on HDD, have tried "old" and latest drivers as well. L2 doesn't eat more memory than it should and still has enough for extra clients. Any pro could help?

for what i read around ... it report ram as problem...but has nothig to do with ram

simply remove client, and reinstall

(or try another client/ system. i m uploading mine in 4shared http://www.dragon-network.net/download.php or use link to client me and track posted in last 2 days)

I must confirm this happened to me too. Reinstall might not help.
Somehow L2 sees less memory than what is actually there ?
