When you say you copied the Thunderbird folder into the profile folder, did you do exactly that? You want to copy the Thunderbird folder into the C:\Users\windowsusername\AppData\Roaming folder:

I created a new folder in the profile builder and posted the complete folder in there over writing the files.

Without knowing exactly what folder you created and where, I recommend you follow the instructions in the link provided. Delete the Thunderbird folder under Roaming on the new computer, while TB is closed, and copy the Thunderbird folder from the other computer into the same place under Roaming.

Allow the viewing of hidden files and folders in order to access Roaming.

Excellent worked perfectly, although I don't know what was wrong with the other location I had created. I would like to put the default folder in a different location to make it easier to backup, what is the best way of moving the folder to a new location.

If you want to store the mail folders in a different location:

If you want to move the entire profile to another location:
