[SOLVED]error when uploading file with tv

As an idea from the demo site of Susan Ottwell (www.sottwell.com), I added a TV to be able to upload a file when creating a page. I get the tv on the page co create a page, and I can try to upload a file. However when I click upload, I get the following error:

Error, "Failed to upload file, internal error..."

I run this site locally on a wamp server. Anyone has an idea to fix this?

turned out I didn’t have write acces in the directory , give the directory write acces and everything works nicely:)
