Hi, my main is currently unable to play. I was stuck in p. Windy mid zone for 2 days with a 3001 error when trying to log into the character.
After many chats with email support and GM I deleted one subfolder from the user folder [which ended up being my alts user data for macros and saved settings]
And was able to log in and play for about a hour. While zoning into P. Jeuno i got 3001 again.
This time I could not replicate the fix, I deleted the same subfolder, tried deleting the other subfolders, then eventually the entire user folder, none of which fixed the issue.
The entire time I was able to log in to my alt and play normally, log onto my main account with a mule and play normally.
I have ports forwarded, switched to a new router on the time period I was able to play and things were fine until it wasn't.
The issue initially started on Monday 3/3 and I was unable to correct it last night.

So while I can still play on the main account thru a mule and my alt account with no issue, my main char is unable to login and play at all.

File checks were done at each interval, showing no issue at all.
I play in the US with Tachus as my isp. There has been no functional change to anything over the last 6 months and there was nothing that I switched until last night after I was able to successfully log back onto the game and move around.
