Asset Store Tools - Package Manager - Method Not Found switchactivebuildtarget

Thought I’d take a stab at submitting something to the asset store, but I can’t even run the Package Manager - I get this error:
MissingMethodException: Method not found: ‘UnityEditor.EditorUserBuildSettings.SwitchActiveBuildTarget’.

I’ve set my Build Settings to Standalone.

This is Unity 4.1.

Happens even with a new project with nothing in it. Is this a bug? Or has the Asset Store not caught up with 4.1 yet?

Downloaded the new version today and its working now.

The Asset Store Tools had some issues with 4.1, but a update was released and the tools should work fine with 4.1 now.

Although is good to remind that the version you upload with, will be the minimum version required to the end users, so it is always a good idea to submit your packages using the lowest unity version possible, this way you maximize your possible audience.
