Since yesterday when ever i click on an app and try to install it it crashes with this message process com.android.vending has stopped unexpectedly. ive turned off the phone several times. but no go. any ideas other than hard resetting the phone. i've got so much installed on the phone.

I've got an idea for you that I believe should work. What you need to do is go into your general settings and then applications. According to which version of android you're running you may need to hit your options/settings button and choose filter and show all running applications. Find the market. Hit clear data/ clear cache and you should be good. When you reopen the market it'll make you click through that you agree to the terms, but you won't lose anything. All your downloaded stuff is saved to google's servers so it'll refresh automatically when you reopen it. See if that helps

Thanx for the reply
But I already done that but no go.but I've noticed I can't access my sd card out says I have to format it. I guess there is a major problem with the phone.i think a hard reset is in order.crap I have to download everything again. Thank for the help though.
