I have the same issue with some others on this site, when I go into VS 2008 I get the message "The add in 'Resharper 3.1' failed to load supplementary package ']]>' etc".
I've tried the suggested devenv /setup and devenv /resetskippkgs but no joy, have attached logs although they don't appear to add much.

Should also have said, after install (and uninstall + reinstall) I get no menu item. I have to point VS at the R# location for it to pick up the addin at all.
