Blocks don't show up after install of Drupal CVS

I just installed Drupal CVS-version of July 18 2006.
Immediate result:
*My sidebars don't show up (That is, no blocks show up)
*The text in each of my primary links is replaced by the text "Array"
*I get the following error, constantly showing up on each page (still no sidebars):

user warning: Table '--my-database-name--.drupal_blocks_roles' doesn't exist query: SELECT DISTINCT b.* FROM drupal_blocks b LEFT JOIN drupal_blocks_roles r ON b.module = r.module AND b.delta = r.delta WHERE b.theme = 'MyThemeName' AND b.status = 1 AND (r.rid IN (1) OR r.rid IS NULL) ORDER BY b.region, b.weight, b.module in E:\--my-drupal-path--\includes\database.mysql.inc on line 121.

I tried with a previous CVS-version before with a similar result. The latest CVS-version that seems to work for me is the one last updated 3 June, which I installed due to quite a big performance problem in locale using i18n and OG, (reported here: http://drupal.org/node/65801).

I'm using the patched version of i18n proposed in that thread, and OG v 1.110.2.99 2006/06/18.).
I'm running ApacheFriends XAMPP Lite version 1.4.16, which includes:

+ Apache 2.0.54
+ MySQL 4.1.14
+ PHP 5.0.5 + PEAR (basis package)
