Supporter Plugin with Multi-DB and Commander

Hi,
I'm running Multi-DB and Plugin Commander plugins. I uploaded Supporter plugin and my admin page went blank. I saw where someone had a Supporter conflict with Commander so I've included it in my post.

This is what I did:
1. Uploaded Supporter files to directories according to instructions.
2. Uploaded the 2 Paypal files to /home/admin/public_html (My root? per instructions. "admin" is my user account on VPS. My WPMU site is in the public_html folder).
3. Created db tables in "admin_global" database (my main blog is in "admin_vip1" db).
4. Refreshed admin page, it went blank.
Where should I begin?
