Upgrading Drupal

I'm a newbie with almost no php experience but I installed Drupal 6 easily. Configured many things, and finally realized why poorman's chron was invested, so I installed it. An hour later I was informed that my VIEWS module needed updating, and thinking the update was as easy as dumping it in my sites/all/modules folder, I dumped it in. Now my whole site is down. All I get is "Page Not Found - The requested page could not be found."

I had some major issues when upgrading a Drupal install from 5.7 to 6.2. It appears that some of the processes that are part of the 6036 upgrade of the system module may not have been done (a couple processes in mysql ended up locking each other and had to be killed). How can I determine what these were and check the database manually to ensure all is well?

I had to entirely errase all my info and reinstal Drupal 6.2 due to too many errors. I need to use my backed up file to replace my site www.janettedengo.com It is right now a blank slate. I have no clue on what to do with the backed up file, I found it however. I did not want to mess with that, as I am unsure with my next step. Do I extract it, copy it, etc.?? If someone could help that would be hugely appreciated.
Thx. Janette

I wonder if anyone can help me out with this? Having upgraded from mySQL 2.3 to 4.0 I now get a page full of errors when I access my Drupal home page.

Here's the first few lines

or as I saw on this forum that have to do 6.0->6.1->6.2?
I got blank page when I do 6.0->6.2 directly.
TIA

I recently tried to upgrade to 6.2 but that didn't work.
Then I decided to re-upload my Drupal 5.7 installation that I had backed up before trying to upgrade.
I imported the database file and uploaded the files of Drupal 5.7.
I ran the update.php script, which worked just fine.
