All hosting accounts should have a linked forum account, which is to be used when requesting support as we can then pull up account information easily by a simple click, it also because of that it is important that you always request support with the correct forum account in case you have more then one forum account.
garypeg (garypeg.x10.mx) is linked to the forum account: pegngary84
panamapg (panamapg.x10.mx) is linked to the forum account: pegngaryubuntu43
The error message you included earlier in this thread indicates that it is the panamapg account you have problems with, hence the confusion here.
Warning: require(/home/panamapg/public_html/wp-includes/load.php)
Did you make that backup through wordpress, or through phpmyadmin?
As for installing WordPress, I'd recommend going to
http://wordpress.org and downloading the package from there (which I always recommend over using an automated installer like fantastico or softaculous). Upload all files, create a database and a database user and link those together (easiest here is using the database wizard, make sure to note the password down as you'll need it later). It's rather simple and doesn't take much time:
http://codex.wordpress.org/Installing_WordPress
You should be able to restore your wordpress into the database afterwards (either through phpmyadmin or through wordpress itself, depending on how the backup was done), though since that was on a different domain it will likely include a little extra work to get functional under the new domain:
http://codex.wordpress.org/Moving_WordPress (the section "If you have accidentally changed your
WordPress site URL" would be the one of interest here, as the procedure is the same).
