The connection issues for the European megaservers have been resolved at this time. If you continue to experience difficulties at login, please restart your client. Thank you for your patience!
bumping your own thread over and over isnt going to fix the problem. apparently as you have three replies since june 20th, its just you. Call tech support because again its just you.
Had a similar issue a while ago. Problem back then was the Craftstore Addon but it got resolved shortly thereafter (Author is very active and quick with bugfixes).
So if you use the Craftstore Addon i would recommend to update the Addon and delete your Saved Variables (usually under Documents\Elders Srolls online\liveeu\savedvariables) for Craftstore.
