I tried connecting again, but this time it said:
"Error: Downloaded file mods/iceobscurity/mp_obs.iwd can not be read"
So I tried getting in the game as an administrator but it said the same.
Then I searched for the mod files and found these (look at the photos).
I also deleted the folder of iceobscurity and tried to reconnect to the server but still the same.
I have no idea what to make of these or even why today is a different case than yesterday, but I thought maybe someone with more experience would.
I guess I 'll wait for rami to send me the files. Nevertheless, thanks for all the help guys!
