Failed to Save Task List

First off, YES I have read the FAQ and the other threads on this topic, most of which are very old.
I have BitComet 1.34 and Win 7 32.

I was torrenting just fine as of yesterday, but today when I try and add any new torrents I get the message Failed to Save Task List! C:\Users\user\AppData\Roaming\Bi...\Downloads.xml

I have the system.use_app.data set to True, and when I go into the BitComet folder, it's set to read only. I uncheck Read Only using my Administrator Priviledges, but no matter how many times I do that, it just keeps resetting to Read Only.

I don't know why it randomly started doing this, I didn't change or uninstall anything.. is there a way to fix this?
