My hard drive died and I had to buy a new one and reinstall everything. After the reinstall, updates were fine, but a week later, software updates won't launch. Mac mail won't launch either. I cleaned the cache with Onyx, but that didn't help. I finally just deleted mac mail and installed Thunderbird -- that fixed the mail problem but not the updates. I am not sure if this is related, but I also tried downloading Soundslides, and the program won't launch either -- any help?
