Maybe try a bigger board to get started. (i got started on a whopping 172 x 42 twin tip with an 05 kite)
Here's one excersise that got me upto riding the board.
As long as you've got enough beach not to be a nuisance:
(not great if you have bad knees)
sit on the beach flying your kite from one side to the other using the kite to pull you to your feet and skid on your heels a little way. this helps you get used to the feeling of getting up on your feet. Do this for 20-30 mins and by that time you should be able to do it without looking at the kite. This will also help you put board on feet while floating and flying the kite.
It might take longer but, full credit to ya, you must be a persistent person. 12 months and only once on a board. I woulda quit by now.

Keep going it is well worth it.
