Getting lots of errors on google from my site.

Hey I just bought VBseo.

I have just for the first time checked vbseo sitemap to see if its beensending.

and I checked the progress of the sitemap with google and it says this.


More than 10 of the pages we've tried to crawl have returned HTTP errors.
More than 10 of the pages we've tried to crawl have returned unreachable errors.
More than 10 of the pages we've tried to crawl have returned timeouts.




Its also saying it was last submitted SEP 20 but downloaded 10 hours ago.


Does this mean the sitemap is really old that google has? And why is it not downloading the new ones that generate?



EDIT:


I think I may not have had the newest version.

I'm deleting everything of the old one, and installing the new one to start fresh.

See how it goes.



EDIT 2:

This is the message I get after running it.

So that looks like a success.




How often should I add the sitemap.txt.gz to yahoo? and how often should google get it as well?

Thanks
