BadImageFormatException starting Development Server

Good day everybody,

I'm trying to use the Nonoba API for my first attempt at making a multiplayer game.
When I try to compile and run the Development Server however I get a BadImageFormatException: Could not load file or assembly 'Development Server, Version=1.5.3.0, Culture=neutral' or one of its dependencies. The module was expected to contain an assembly manifest.

It happens with every supplied example game (Fridge Magnets, TicTacToe etc.).

I'm running Vista Home 32 bit, and as the serverside IDE I downloaded Visual C# 2008 Express.

Did somebody get the same error?

Same results with Visual c# 2010 Express. By trying and retrying (and reopening the IDE, and rebooting Windows) it seems that also Nonoba Game Library is part of the problem:
Resolved file has a bad image, no metadata, or is otherwise inaccessible. Could not load file or assembly 'D:\Flash\SDK\NonobaServer\Nonoba.GameLibrary.dll' or one of its dependencies. The module was expected to contain an assembly manifest.

Curious, it just worked... outside the IDE: I double-clicked on TestServer.exe and it ran fine.
