Problem with Problogs Beta 6 and Multi DB

I have been testing ProBlogs Beta 6 with different configurations of MultiDB (256 and 4096) and with the default DB and whenever I use whatever configuration of MultiDB, I am unable to save the settings of ProBlogs (what actually happens is that whenever I save the settings, the entire settings page returns to default). If I use the default Multisite DB configuration I am able to do anything with the Beta version and do not get the problems associated with MultDB use.

The 2 installations have worked well till the problogs beta testing and have been configured exactly as directed. Any inputs are appreciated. Topic is also posted on the problogs thread but I figured this was more a MultiDB problem than it was the Beta 6 problem.

Here is a copy of my db-config.php file for my 256 setup (very much like the 4096)
