Proper way to close a project and start a new one

I seem to have problems when I try to start a new project (makes me try again several times). I was wondering if this is common or if I am doing something wrong.

Any thoughts? Thanks!

What steps are you taking when creating a new Project?

Make sure you don’t end the project path and name with a slash. For some reason, doing so causes Unity to crash.

I’m simply going to File>New Project. It’s happened on a Vista box and a Windows7 box.

Ok, but from there what exactly happens. Step by step, where does the process get confusing or stop working for you?

What are the project names? (just to ensure you don’t have asian letters or alike, unity does not like them in the project paths when I remember correctly)
