Problem found: sh*tty windows 10 makes documents folder read-only. I tried to change permissions but this is even sh*ttier in windows (all hail the mighty tux). after almost 1 hour all attempts to change folder permissions failed and i gave up with this.Try running the program as administrator, if it doesn't help, go the folder option and check if its on Readonly mode > if so, remove the read-only.
Otherwise, check if your antivirus has an option to "protect from files to make changes" (like HIPS of ESET Smart Security) if so, you will need to change it so Warcraft 3 can make changes.
There is another problem with gproxy and possibly related with this patch update. While game working as usual it just disconnects from server and gproxy dont even try to reconnect. game gives you were disconnected prompt and server connection failes randomly. This happend yesterday first and second time today. Also under unban requests at lagabuse there are lots of ppl having this situation fyi.
I forgot to get log file after dc and started another session but if i get disconnected again like this i ll post log file also.
