I solved this myself.

This is what i did:
1) I copied the nextgen gallery plugin folder from the 1st server (it’s an older version), and copied it to the 2nd server.
2) I exported the ngg tables from the 1st server and imported them to the 2nd server.
3) I then updated the nextgen plugin on the 2nd server. When i did that, it notified me to click a link to update the database tables, so i clicked it and it updated the tables.
4) * It’s now working fine.
