How to run a backup of my forum on PC?

[mp3president]

Hello,

Don't know if this is the good section to put this in, so sorry if it isn't.

I have a problem with my forum. A Admin accidentally deleted a lot of posts from a user.
Now i want to extract them from a previous backup and import them on my forum.
I have a backup from a month ago where al his posts are in.

I want to put the backup from my forum in xampp, so it runs on my pc an go on from there.
I installed xampp, put the backup in a folder, imported the database in phpmyadmin using bigdump (there my database is over 700 MB).

But when i want to start the forum in localhost ( localhost/forum/forum.php) it does nothing.

I went to search on google for a tutorial, but only find new installations.
Have done that a while a go and that works, but can't get a backup working.

Does anyone know where i can find a tutorial or something???

Sorry for my English.

Greetsss
