Normally, if you go into your phpmyadmin you can do whats called an SQL dump to add the information into the tables....but....(there is always a but :p) the problem with having done a fresh install, is that all the modifications that the upgrade scripts do to the tables aren't going to be applied to your backups by doing a dump...so 9 out of 10 times, you'll get SQL errors about counts or unknown columns etc....
Your best bet as much as you don't want to hear this....is probably to re-run your install from whatever version you WERE running...and rather than doing a fresh install (which truncates all your tables) click the upgrade link above it (you can't miss it....its in big letters) and run through the steps to update your tables and the rows in them to the current release version
Someone might beable to tell you an alternative to cut down how much time it takes you....personally, i'd rather do it the long way cause then I know I won't run into hiccups.

Thats a matter of preference more than anything
Hope it helps!
