Upgrading Drupal

We have had no known problem for the last 6 month, but recently we discovered issues with our site and noticed the panels were not populating in addition to some access limits and missing fields in some of the modules. We were either hacked or our host had server issues, disk error, hardware failure, etc.

Computer 1: Windows7 Ultimate 64 bit
Computer 2: Windows 7 Ultimate 32 bit
WAMP v. 2.2
Drupal v. 7.12
CiviCRM v. 4.1.1

Getting read/write error in attempting to install CiviCRM module after upgrading to Drupal 7.12

Going back to the previous version of Drupal gets same error message. Now I can't create CiviCRM module under any circumstances. It used to work fine before the upgrade.

Have tried setting Read/write priviledges on c:/wamp/www/drupal/sites/default/files folder

deselecting readonly checkbox with no effect.

We are not able to install the software. Please see below for details.

Database Version and Connection Settings

CiviCRM stores its content in a MySQL database. Please provide the username and password to connect to the server here. If this account has permission to create databases, then we will create the database for you; otherwise, you must give the name of a database that already exists.

Database version and connection settings have been verified and look correct!

CiviCRM
Is the C:/wamp/www/drupal/sites/default/files folder writeable?

The user account used by your web-server needs to be granted write access to the following directory in order to configure the CiviCRM settings file:
/C:/wamp/www/drupal/sites/default/files

Hey,

is there any known bug with the drupal 7.12 upgrade? I have a large database from phpbb and now no password works! The upgrade from drupal 7.8 was correctly and no errors was shown. I try to copy the user database in a new installation of drupal 7.12, or copy manuell some user datas, but i still get no access. Maybe the encoding is wrong ... has anyone an idea?

Greetings M

Hi guys!
I need your opinion. I'm totally new in this game. Haven't worked with any cms before (I've looked around a lot though) and I'm no hacker. I know Drupal is consider to be hard to learn, but it has what I want, so I'm going to do my best. My first concern is if it's best - for me as a beginner - to upgrade Drupal to a higher version ( if yes, which version?) as the first move or just go with the Drupal 7.12.11 that is successfully installed an go right on to install some modules I need?

Thanks in advance!

While upgrading from 7.10 to 7.12 I got the following error:

register_globals is enabled. Drupal requires this configuration directive to be disabled. Your site may not be secure when register_globals is enabled. The PHP manual has instructions for how to change configuration settings.

Just wandering if I am following the correct steps in upgrading
