Ok, really problem that's also really hard to describe! Basically, I had most of my downloaded applications on my SD card. Now whats happened is, none of the applications from my SD card will load and I have no idea why. I also can't connect my phone to my computer as a disk drive. I'd previously had set my default install location on my phone to SD card but I've changed that back to phone now. When my SD card was not inserted, after doing this I was able to download applications from the market but now I am unable to do even that! What's even more confusing is my photos and music on my SD card load just fine on my phone! ANY help on this would be much appreciated. Thank you.
