That isnt a fresh .RPT (first time you started the game was 2010/07/19) to make a fresh .RPT just delete the old one and start the game, make sure you remember that for any future problems as others would just ignore the .RPT all together.
Right reading it it seems you are still using the orignal version of the game... v1.52, that game has been patched to v1.57 with v1.59 about to come out soon, so here
is the patch you need just run it and start the game after it finishes your problem should be fixed (till at least the next version releases), make sure to check here at least once a week and catch up on the latest news on the home-page (make sure to go through the pages until the last news you have seen) also going to the official arma 2 site
wont hurt, you can subscribe to there rss to get all the latest news without visiting the site, they always post there latest patches news there.
