Rfactor requires unknown base mod??? [Resolved]

[Harry Walker]

Hi,

So I have purchased Le Mans and the GT3 Challengers pack however I am not able to get into any online sessions.

Whenever I try to join a server I get the message below (it changes between cars).

I have tried unsubscribing and resubscribing to the workshop items - with no luck as well as removing "mod" packages from servers.
Any thoughts on where I should go next?
Thank!

This happens for all the GT3 cars from the challenger pack. I am able to use them in single player, just unable to connect to a multiplayer server.

I had to reinstall to resolve this issue.
