UMC not downloading.

[RoyalSnake]

Happens every time I try to download some UMC.
Version is 1.15.4, Steam.
You know, it says that there was some kind of problem while trying to generate the required archives for the complement. Tried with a few UMC, same results.

Sometimes I don't have problems at all. Idk if it's something related with the newest version, because last time I tried I downloaded some campaings.
So what's happening?
Thank you in advance for your attention. (:

So basically I tried to: download some campaings, ie. "Antar, son of Rheon", "Bad moon rising", "After the storm", and maybe one more, just for the try, all with the same problem.
The download bar fills, but then the message appears.

Also I tried to launch "To lands unknown", which I had already downloaded from some time, but it didn't run. It just says "Fail to load scenario". Don't know if it's related.

As said above, I'm on Steam version, 1.15.4, Win10.

Thanks.

One Drive is known to cause issues when it's used to handle Wesnoth's add-on directory. Checking whether any sort of security software is restricting access to that folder is something else to check.

Nice. I just had to disable OneDrive. Now my Wesnoth is fine. Thanks for your time.
