Files not viewable after upload

Am running on Windows Server 2003 with the premium plugin. The folders get created correctly, I can upload just fine, the files are listed on the backend, but not in the actual view finder itself.

What I’ve done:
1. Read this: http://ww.wp.xz.cn/support/topic/uploaded-files-doesn%C2%B4t-show-in-list
2. Disabled/renabled plugin
3. Disabled all other plugins

What else can I do to fix this?
