Can you help? Im going mad and bald with fustration here. Your more familair with myphp etc ...

OK, heres the picture... Sorry if this is long winded but I want to explain this as best I can so maybe you can help.
I'm rather newish to PHP and MySQL however I think im begining to grasp some of it now.
Heres the story.
My website forum hosting provider has an PHPBB2 auto-install facility which installs PHPBB 2.0.8 within a few clicks etc. It creates the MySQL database and its up in no time at all. I have recently plucked up the courage to update to PHPBB2 Plus 1.52 which has a portal and forum incorporated.
All is well and its been running fine until a freaky thing happened this morning. I was trying to do a similar install to a different location using the auto install so I could trial out some themes for it (safely) when it came up with "There was an error with the install". Subsequently, it fuxed up the existing portal/forum so It couldnt connect to the database. This drove me nuts, but luckerly I had backups from the day before. I did look into the database but really couldnt see where the problem lies. Anyway, ive since had to drop the database and start again.
I had 2 backup types. One was from within the admin panel within the forum itself. (full backup) The other was a complete backup from phpMyAdmin.
The problem:
The problem I have is that Ive managed to auto-install and update a fresh install to PHP Plus and restore the tables into the new database using phpMyAdmin backup. So far it all looks as it should and is up and running. However only the portal data is correct. The forum is blank. !!! The strange thing is that all the members and number of posts in the forum (1000 odd) are showing in the stats box of the portal, but when I click onto the forum, its just a blank forum as if it was a fresh install. No posts at all.
After this I dropped the tables in phpMyAdmin for the database and tried restoring it in phpMyAdmin using the backup I did from the forums own admin panel. This just times out and takes about 15 mins to say that. Ive tried this 5 times now, same result. I have also tried restoring using the forums admin panel php but eventually it says No File Was Uploaded.
Ive gone over and over and over all the admin panel settings and they all point to the right location. I really cant seem to see whats going on. Whats even stranger is that an Annoucement News Article is showing in the home page of the portal which is posted via the forum, but I cant access it from the forum because its blank.
Its as if the data is there, but the forum isnt looking for the data in the right place.
Anyone here able to help or suggest anything?
