Google Reader Issue

Now I know that this may not be the right place to ask... But I figured it might be worth a shot or some more insight might be provided here.

I'm currently subscribed (through Google Reader) to track "My Friends" Blogs here at GS. They show up fine in the reader... You see the title, a preview of the text, everything is fine and dandy. However, it is when I actually click on the title (in order to take me to the correct GS page) that I run into a problem. 

GS gives me an error that says "Username is either invalid or unregistered."

I don't know if anyone has any idea why that happens, but hopefully someone knows

Thanks in advance!
