Installing and upgrading help

So, I noticed that fantastico said that a update was availiable for moodle, and decided to do it, in hope of curing the language pack instalation hang that used to happen.

Now im locked out of my moodle, because it keeps asking for upgrades to the server, most of which I already done. I'm not entirely sure that he is in fact cheking for the changes, because he always conplains about the same stuff, even if I already did the changes.

unicode		must be installed and enabled It is required that you store all your data in Unicode format (UTF-8). New installations must be performed into databases that have their default character set as Unicode. If you are upgrading, you should perform the UTF-8 migration process (see the Admin page).	Check
php_extension	zip	must be installed and enabled The Zip PHP extension is now required by Moodle, info-ZIP binaries or PclZip library are not used anymore.	Check
php_extension	xmlrpc	should be installed and enabled for best results The xmlrpc extension is needed for hub communication, and useful for web services and Moodle networking	Check
php_extension	soap	should be installed and enabled for best results Installing the optional soap extension is useful for web services and some contrib modules.	Check
php_extension	intl	should be installed and enabled for best results Intl extension is used to improve internationalization support, such as locale aware sorting.	Check

There are the errors he sees, and I worked on most of them, especially the first 2. One of them requires to mess with the php.ini, and I had to contact my host to make the change, so im fairly sure it's good (got an email confirming the change and everything).

I also did try a new instalation with the 2.0.2 (in the same server) and noticed that everything is working, so either the changes are already done and the old moodle isnt assuming them, or the changes aren't really vital to have moodle running.

Can anyone help me? I wouldnt mind a roll back to 2.0 to get rid of these errors, but for some reason I assume that's not possible (without losing info). Either that of "saving" the courses I already did and pass them off to the new instalation (The moodle I did isnt active yet, so there are no users, I just had some work doing the courses and dont want to lose them).

Thank you.
