Cannot set import 'Telerik.BlackDragon.Client.IceniumPackage.SimulatorService Error

I am trying to add a AppBuilder -> Kendo UI Mobile project from the Project Templates to an existing solution. However, it is unable to create the project and pops up dialog boxes with error messages. The final error message is that .iceproj is not registered as a valid project. On opening the ActivityLog.xml file, this is the error I see:

<entry>

    ContractName    Telerik.BlackDragon.Client.Mobile.Simulator.Services.ISimulatorService
    RequiredTypeIdentity    Telerik.BlackDragon.Client.Mobile.Simulator.Services.ISimulatorService

Resulting in: Cannot set import 'Telerik.BlackDragon.Client.IceniumPackage.SimulatorService (ContractName="Telerik.BlackDragon.Client.Mobile.Simulator.Services.ISimulatorService")' on part 'Telerik.BlackDragon.Client.IceniumPackage'.

Any help available?

Oddly enough, once I removed AppBuilder from VS Extensions, closed VS, reinstalled the .vsix and reopened VS2012, it started working.
