I upgraded our CF9 to CF10 today. I had CF9 installed in e:\coldfusion9 so I installed CF10 in e:\coldfusion10. It asked if I wanted to run CF9 and CF10 at same time or run all apps in CF10. I choose to run all apps in CF10. After the install I tried accessing admin page, but after login prompt I get:

The DataSource service is not available.

I've tried turning off CF9 services without any luck. I'm running Windows 2008R2 and IIS.

Any ideas?
