Stuck at loading screen (book) - nothing works

[Lioneyes]

Same old story but things have become worse...
Last time I managed to log in, I tried to use a flight path to IC and I was back to the menu screen. From then on I have been trying for hours to log in to the server with ANY of my characters and it is impossible!
The game stacks at the loading screen and then back to the menu screen. I have tried ALL I have read on the forum. Command /stuck x2 simply changes the loading book to Norsca but I still get either stack at the book or back to the menu screen. I have deleted and re-downloaded a supposedly corrupted file (world.myp). No change.

The problem started 3-4 days ago and all of a sudden. No change in the hardware or software of my PC.

ANy suggestions? I really start losing my patience...

Update: I restored the file world.myp from the recycle bin and I managed to log with my main char in Norsca (after using /stuck x2). I deleted ALL the quests as suggested by some players with similar problems. Hotfix is taking place and I cannot check if I will be able to use flight paths or any loading screen without disconnecting. I will keep updating.

Update 2:
I can log in now and play. However, everytime I get a flight path to any city, I get the menu screen.
