Problem Signature 09: System.OutOfMemoryException
Is this occurring when you are opening WebMatrix or when you are running a site / application in it? An OutOfMemory exception is generally going to occur if you attempt to store a large number of items into memory (and the amount exceeds the available system
memory). It can also sometimes occur when you encounter an infinite loop.
If it is when you open the application, I would highly recommend re-installing WebMatrix as it sounds like something might be wrong with your existing installation.
