TRUNCATE error -1 obliterating my sites
Why are these paths different when you talk about "your project":

path 1:
C:\Program Files (x86)\EasyPHP-DevServer-14.1VC9\data\localweb\projects\web2\includes\cache.inc

path 2:
C:\Program Files (x86)\EasyPHP-DevServer-14.1VC11\data\localweb\projects\webONE\includes\cache.inc)

This smells like something is horribly misconfigured.

I've made dozens of drupal sites, typically under Linux, but I have used WAMP myself in the past (not EasyPHP-DevServer). This makes me think it's an issue with the EasyPHP-DevServer and not drupal itself.

While you may not be familiar with it ... have you tried like copying your site files and DB to a Drupal 7 Quickstart project VirtualBox virtual machine, or  DrupalPro ... another off the shelf VM drupal-in-box ...
