Sharepoint 2010 Javascript errors

After installing Sharepoint 2010 beta on my box, I got javascript errors on page load and many UI functions are not working correctly;

Sample of javascript errors:

Error: ‘SP.Res.autocompleteLoading’ is null or not an object

or

Error: ‘SP.Res.lcid’ is null or not an object

 

Also this errors appears in the centra administration site,

 

The Solution:

well after searching and troubleshooting I figured out that there is a virtual directory "/_vti_bin/sts" has assigned an application pool "SecurityTokenServiceApplicationPool" that is not existing on my computer after fixing this problem and assigning another valid application pool the problem is solved and everything is functioning as it supposed to.
