Monotouch: "Unknown solution item type" after upgrading

I recently just upgraded to Lion, upgraded my XCode install, and also upgraded to the latest MonoDevelop via the updating tool in the app. Once all the installations were done I tried to load in my project that I've been working on and get the following error:

"Error trying to load the project 'Users/filepathstuffs/project.csproj': Unknown solution item type."

The other thing I have noticed is that if I try to start a new project I don't even have the option anymore to start an iPhone or iPad project. Any help as to why this could have happened and what I can do to resolve it would be greatly appreciated.

Update: This is resolved. Poupou was correct in his assumption that the MonoTouch version was out of date. If upgrading to Lion your versions should look something like this

OSX: 10.7 Xcode: 4.1 MonoDevelop: 2.4.2 MonoTouch: 4.0.4.1

For some reason the MonoDevelop add-in manager didn't recognize that the MonoTouch add-in was out of date. I had to re-download and install from the website.

It looks like your MonoTouch addin is not up to date. Can you please edit your question and include all version numbers, e.g. MonoDevelop, Mono and MonoTouch (even xcode). - poupou
Thanks so much Poupou. The issue was that everything was up to date except for my MonoTouch add-in. It's weird that the add-in manager didn't recognize this and offer me to upgrade but alas the problem is resolved. For anyone else upgrading to Lion and in turn Xcode.. I would recommend updating MonoDevelop and re-installing the MonoTouch add-in because the add-in manager didn't recognize it was out of date. - ry_donahue
