Elllo there, @W44h1b
First of all, welcome to TruckersMP Forums here in Help Section.
My name is RedNub and I'm member of TruckersMP.
According to your issue you mentioned please read following steps:
Firstly make sure you have steam set up to public
- > Have you tried to launch TMP as administrator?
- > Does it always happen when you want to enter in to MP?
If you have recently bought some dlc, I recommend you to check all dlc here: https://truckersmp.com/profile/settings - Linked DLC's - > click to check dlc and wait.
2. Solution - > Clean a cache and cookies in your browser, try to re-login again and check DLC's and wait.
I'm waiting for your response
Kind Regards,
RedNub
