I thought I would download and give Sublime Text 2 a try as I wanted a good HTML/CSS text editor and I was fedup of Dreamweaver. I installed it but I just can't use it, a few seconds after opening it comes up with error boxes and I have no idea why this is a clean installation. Please see this screenshot below:

It seems to be having trouble connecting when downloading package information (404)... could someone help me solve this?... I can't use the program because of it.
-thanks
