Well I feel kind of dumb...
I've updated my Blackberry's OS many times but this is the first time I have run into a problem. When I run apploader, it gives me a list of apps that I have, then I press next and it gives me this screen -

I know that I have the OS installed on my computer and it's not the same OS that is on my phone (I'm running 6.0.0.526 and upgrading to 6.0.0.546).
Anyone know what the problem could be?
