Unsuccessful at upgrading Thunderbird 0.7 or 0.8

I cannot upgrade to Mozilla Thunderbird 0.7 or 0.8. I am using 0.6 without any problems. When I install 0.7 or 0.8 I receive this message " Alert - Could not connect to server
Pop.west.cox.net; the connection". I have perused the FAQ and help forums for Thunderbird but could not find any information with regards to my problem.
I have XP Home with SP1. I tried deleting NAV 2004, then installing 0.7 and 0.8 with no success - same alert.
I am using a Netgear GT624 router but I don't see any connection. I am extremely satisfied with Mozilla Thunderbird as my email client but I would like to upgrade.

Thank You, but I already have a number of downloads of Thunderbird 0.7 and 0.8. What I want to know is that after I install it why it won't connect to the ISP. I am running 0.6 now and everything works just fine.

Did you update/import your profile?

Thanks for your post. I've spent over six hours trying to update/change my profile with no success. Right now it's not worth the time wasted. I will stick with Tbird 0.6 or go back to outlook express. If this software could not be designed for an easier way to upgrade and work, then I don't see any difference from Microsoft Windows.
