Minimwatch won't load

[Avalon]

Hi,
I've had a look through the forum but can't find anything specific to my problem.
Minim watch won't load anymore since my last Java update on my windows 7 laptop.
I use minim server on qnap, it used to load with a little green box and I could rescan the library from there, the box stays grey and the options to refresh and scan aren't highlighted anymore.
It must be Java but I don't know how to fix it.

Thanks

Avalon
