I contacted with SM support and they gave an usual solution: delete your preference files and if that doesn't work reïnstall poser and use the latest service release. I did that twice and the library still doesn't work as it should be: it does something but it seems to work extremely slow.

I checked my firewall settings, but poser is allowed to access the internet as it should be.
