Good luck.

I deleted the bwps records in the _option tables of all blogs, after I installed bwps again. I always manually edit .htaccess for rewrite rules, so that was not an issue. Everything sweet now, problem solved : -)

Thanks Handoko for all your efforts and quick response.
This is an essential plugin!
