Help with Sublime Tect 2

Hey guys I have a huge problem and figured that the friendly Null-Byte Community could help me out with. I've started using Sublime Text and it is awesome. I have already designed my first website on it. However, when I started my second website, I realised that separating the two projects would be a wise move. However, since I didn't know anything about projects, I accidentally mixed the two. Thinking it wasn't a big deal, I just deleted the projects and was about to open the files I needed individually for each project. However, now the files wouldn't even open.

And it reads 'project could not be found' when I open any of the files, and even when I start up a blank document, a notice that says '... Project could not be found' everytime I start up sublime text. I've tried everythingn, from re downloading the files (I hav them on my email because I emailed them to my partner), re-installing the app and so on. Help please??
