Disregard, because it seems the problem is solved right now.

I created a new usergroup that can upload files and I added only 1 user in this group.
Now, this user is trying to upload files, at a certain point he got the error message

I read in this thread that a user had the same problem. I won't create a .htaccess file, because I think that's not the problem; what i think, which you actually mentioned in one of your replies, is that there's a problem of "crossing" permissions if this user is a member of 2 or more gropus. This user is a member of an old usergroup in which has beed added the settings for Download mod (which i actually didn't think it would act like this, I mean i thought the mod would not add its setting even on old usergropus). Now, in this old usergroups the Download mod settings has not been touched and everything is set to "no" (can't download, can't upload, and so on): The question is, obviously, the following: the permissions about the new usergroup "rewrite" those on old groups? And in this case, i don't want to set the same permissions on every old group I have, simply because I want that only that single user can upload files. Now, I know that my english is not that good, but please, help me!
Thanks a lot in advance

ps: I forgot to better underline the most important fact: that user could upload several files, it's only from a certain point on that he could not upload any more.
My setting in the new usergroups are the following:
