I have tried everything and can't seem to open my market place app. Plus my phone freezes ALL THE TIME! Please help!! I can't wait until January to get my upgrade. Bye Bye Incredible. You were a good "starter" smartphone.
Try clear the cache or even the data for the Google Play Store app. Settings > appplications > manage applications > all tab > scroll down to Play Store > select it and press the "clear cache" button.
