Cosmos Error after updating today?

[BadgerAlumni]

Can't use "/" commands after updating cosmos today... what the heck?

Worked fine yesterday, and the day before.

When I try, this is what I get

String: Interface\FrameXML\Chatframe.lua
Line: 2270
Count: 2
Error: attempt to call global
'CosmosMaster_GetCommandAliases' (a nil value)

Somebody must know the answer here.

Ok, I have rectified this error by deleting both the ChatFrame.lua & Chatframe.toc files, however, I'm still getting an "Outdated Cosmos" in my Main Menu options.

Anybody know the remedy?

Running interface # 4216, etc.
