Thank you for all your support and advice. I got my computer back and spent the whole weekend on downloading content and installing software. I have learned a hard lesson but the lost isn't that much after all. I still have all my foto's, my music and important software which were on an external drive as well with my professional autocad and rhino-files. I had a backup of the mayor part of my poser projects, runtimes and content on another harddisk, but I lost about one and a half year.

I have a complete clean installation on my computer which feels like a new computer and that is always fun. I treated myself on a new set of speakers and  a new backup 6TB NAS-drive, which softens the pain (and a lot of chocolate and wine of course)

best regards,

Bopper
