Uploading errors

So I had been having troubles with uploading a file, and it getting stuck just buffering. I asked what was up on the chat, and an administrator helped me out by uploading it for me, which worked great! Now, however, I was uploading a multi movement piece— oddly enough, the first one uploaded just fine, no problems at all. When i try to add another movement, though, it keeps saying I'm logged in as Crypp2009 at the top, and then the upload fails, and a window pops up that says "not logged in".

I talked to the same administrator on the chat again who suggested a create a topic about it!

That's bad. I'll be sure to forward this message along to get this resolved.

Yeah, I'm wondering if it has anything to do with me uploading the file for her?

I was able to upload a single movement piece today.. but still not adding movements to the other. So it is only when i try to add movements to something that I already posted.

Yeah, I can't add movements to a piece that I posted. It links me to the home page when I click the "edit movements" button.

Here's another upload error: the wiki won't let me upload new files. It tells me "The upload directory (public) is not writable by the webserver."

Meh.
