As you may be aware we just released V0.2 of the XNA AdRotator control which includes a host of fixes, an update to the new pubcenter control and the new Remote texture support for house ads.
We're still working on the final updates for the Silverlight release but if you feel you need to update now (for the new pubcenter control) then feel free to download the source and compile your own version, is fully working (as far as we are aware) with
all fixes applied including the new pubcenter control, we're just adding the remote URL house ad feature at present.
So if you're doing XNA grab the latest release and if your doing Silverlight then either use the source version or wait a little bit.
We've also reverted back to our original release strategy and include all dependant Ad Provider DLL's with the release package to avoid the issue's we've seen with updated controls, so everything you need will be in one package.
Let us know how you get on.
