I recently updated my limesurvey from 1.92+ to 2.00+ and since, I get the error:

Error 6 (net::ERR_FILE_NOT_FOUND): The file or directory could not be found.

when I try a vvexport

I tried to uninstall, download it again and reinstall but the error won't go.

Every other type of export a working well but as soon as I choose my survey and press export in the vvexport section, instead of starting the download, the server show the error.

I'm running it on a Apache 2 server with PHP 5.4 and MySQL 5.5

Anyone having same problem or an idea about how to solve this... which file or directory could it be?

thanks
