Hi Henrik,
not really ....... but we have seen a solution for this problem at other user on this way:
download (again!) the newest version from the PHP Webstat,
make a Backup for your stat data,
set up a completely new installation on your server for the stat,
play back the Backup - and speak a quick prayer
Maybe it sounds crazy - but a couple of user were herewith successful ...
Good luck!
