Hmmmm - good to know! My guess is that this might come from the Coop code (where it is indeed looking in to the CAMPAIGNS folder). At least it's not something systemic that is likely to cause issues for OSX players. Thanks for working this out!

very interesting...do this need to be done only on the MAC or for PC also? It sounds like it may just be a MAC issue...

Are you in PC no? try it, I think it's also on PC.

not seeing those files in the folders mentioned on PC...

Which files?

You should download any MP scenario, for example The Guards, the scenario will be placed in the MULTIPLAYER folder.
You should then copy that scenario folder (not move) to your CAMPAIGNS folder so you'll have a copy of the scenario in the CAMPAIGNS and one in MULTIPLAYER folder,
Then open BA2, and open a challenge of Guards.

Remember that you can see always your challenge, but others (probably not)
If you do that, make an advice so we can check if we see the challenge.
Remember that to test something all steps should be made with precision, accuracy is the key to not get erroneous results.
