I've had this tablet since November and had no problems at all with Android Market. Today I can't install anything - it just says 'waiting to install' after I click Download in the Market app, and nothing ever happens. The one I'm trying now has been running for 20 minutes with no errors or changes on the screen. I have almost 11gb free in internal memory, about 27gb in the external card. The tablet's not rooted, I have a good WiFi connection (at home, where I installed most apps). I've tried clearing both the cache and the data for the Market app, no difference. The app is up to date. When I visit the Market going through the browser and search for the apps that never installed today, it tells me they're ALL installed, but they're not in my apps list and their icons didn't show up on my home screen like usual. I don't get it. Please help, I don't know what else to do here.
