Hi there,
I've had the Breaking Ground and Making History Expansions since they day they've come out. Never had an issue with them. 1.8 was released and changed that. 1.8 functions as expected; however, the DLC appears to not have updated with it.
I get "Expansions Failed to Load" as the error with a notice telling me that the DLC versions are incompatible with the current version of KSP.
Using Steam, I have verified the install, re-installed the game, re-installed the DLCs all to no avail.
Any suggestions appreciated.
