[Plugin: Advertising Manager] I’ve lost add colors when upgrading to advertising manager

I’ve had many sits setup using adsense manager and upgraded to advertising manager.

My origional setup uses Google Adsense channels where I have a channel per website. In addition I used the Adsense Manager Plugin to specifiy the colors for my adds.

My problem is now I’ve lost the colors I’ve setup for all the domains and all have gone to the Google default blue title black text green links.

How can I setup my own colors in each website simular to what I did with the old adsense manager plugin?

I have many domains..

some websites are using wordpress 2.7.1 and some 2.8

Thank you.
