HELP: TP2 Menu's Not Loading

[djtech2k]

I have a TP2 With Sprint.

All of a sudden today my phone was sluggish, so I rebooted it. After reboot, the screen is blank with only the old start menu. I am guessing that the TouchFlo thing did not start. I have rebooted and/or removed the battery 5x now and it still will not launch.

I am leaving for an international trip tomorrow, so I have no time for this. Any ideas how to get it to work? I have not made any major config changes. The last thing I can remember I did was to installed an app from marketplace, but I have not used it and I have rebooted since then with no problems.

I am leaving the US and going to Europe, so I also need to find out how to use my phone there and how much it will cost...if I can get it working correctly.
