Upgrading Drupal

I've installed 6.2 and have it working, but every time I go to Administer/Reports, it shows that I need to upgrade to 6.2.

Why?

I've already tried to clear cookies and history, as well as doing a restart, to no avail.

I upgraded from D6.15 to D6.2 recently and now the views wont show up. For example the contact us page in my site is supposed to be a view that combines all nodes of type CONTACT in a single page and displays it. Though I see the information on the preview while creating the view, when I click on the 'View button at the top, I get a message that the page cannot be displayed. This is utterly confusing. I tried all ways to resolve, like i thought maybe the URL that I am giving for the page is a duplicate and so changed it to something completely random, but no luck.

Hi
I was running a 6.15 version of drupal till I decided to upgrade to 6.2. Post installation, I find that a lot of things have broken down - views not showing up even though the data appears in the preview, broken links, missing modules etc. But I want to ask about the ugly warning message that shows up on the home page. It is user facing and gives a horrible picture!

I have downloaded drupal-6.20.tar.gz, and uploaded all files manually, run update.php twice
but my Drupal show 6,19 version

What can be? I checked all files twise

Status Report is listing all the modules I need to update like it normally does. I've downloaded then uploaded (FTP) the updates to the correct place, but when I run update.php it doesn't recognize any module updates (upgrading 0 of 0). This is the way I've always updated modules, never had a problem before.

Before trying to update my modules I updated from 6.19 to 6.20. Status report lists this correctly. The site seems to be working fine, update.php isn't listing any errors, but this can't be good. How do I approach fixing this?

After installing an update to a module and running update.php, I got the following error.

user warning: Unknown column 'lops-settings' in 'uc_power_tools' query: ALTER TABLE uc_power_tools CHANGE `lops-settings` `lpos_settings` INT unsigned NOT NULL DEFAULT 0 in .../includes/database.mysql-common.inc on line 529.

Is it safe to just re-run update.php? Or should I uninstall the module and re-install it?
