Plugins erroring - FRODO

Hi All

I'm having really odd things happen with my Frodo install, I upgraded from Eden where all was working fine -

Now every time I start Frodo I get a raft of plug-in errors, that flash through, the bottom corner of the screen, also, standard things like subtitles fail ....

Ive re-installed on more than one occasion, and I use MySQL, which I can't see being an issue

any help / Advice much apppreciated
