pdf files won't open

Hi guys. Recently the .pdf files downloaded using wlcpod don't want to open. In Adobe Reader 7.0 I get the "There was an error opening this document" message.

I hadn't had this problem before. I can download those files manually and they will open. The pdf files seem to be downloaded completely using wlcpod, but just do not open. That's the only problem. Anyone know why?

BTW, EditPad Pro works great with the UTF-8 encoding!
