Problem with videodb after salvaging site

Hi Guys

Well I accidently deleted my live site, instead of my backup, so I'm in the process of recreating it,
bringing all components up to date again.
I'm hitting some problems with a couple of things, one of them is VideoDB

For some reason I see a blank page when entering the main page, the URL changes to 
videodb/login.php?refer=index.php%3F
But nothing is displayed.

Is it the cache acting up? What to delete?
I'm a bit baffled, VDB has been very stable for a long time, but of course, now it's putting on a tease 

Best regards
