Tables keep getting moved to C instead of Global DB

Been trying to install an Advertising plugin which keeps on creating the tables in my C database instead of Global while running MultiDB.

The plugin doesnt find the tables in C and asks to add the tables manually. I then run the MySql code in the global database after I've deleted the tables in C..

When that is done, it appears that the plugin is working, but every time I save anything it keeps the defaults of data that was created in my C database.

I've tried all angels but not sure how I can stop the tables from being created in the C database.

Anyone experienced something similar and know how I can fix this?

I have tested the plugin on WP 3.0 and it works fine.
