To be honest, I don't know if it's a windows or a linux server. Though, I believe you are right about my hoster updating the MySQL at the sametime they migrate PHP 5.2 to 5.3.
It turns out that I couldn't install the software because Timestamp (14) was being used on the install.php
I had fixed that and the install went through successfully.
Now in testing the functionalites of the software, I get these errors:
Function eregi() is deprecated in /home/./www/www/././list.php
Assigning the return value of new by reference is deprecated in /home/./www/www/././update.class.inc.php
Deprecated: Function split() is deprecated in /home/./www/www/././calendargrid.inc.php on line 51
Which I guess is a good thing, they seem to be very specific problems and are related to PHP this time,
I found this help manual on the migration from 5.2 to 5.3.

Am going to read it and see if I can't fix it.
Anyways, my eyeballs are fried from staring at the screen for 12 hours straight.
Am going to call it a day. I'll resume my repair quest tomorrow.
Thanks NogDog for your help. Have a good one!
