Software looks like it's Corrupt

I have my Tough TG-1 since 2012. The software on my tough TG-1 needs re-installing. There are various problems here are just two for example.

1. After powering on the screen stays active just for a matter of seconds although the power is still on. I have to keep pressing a button to reactivate the screen.

2. When I look at the videos & photos the screen does not stay stable, it reduces the images to about 8/10 per screen and to a multiple moving screen from right to left so it's not possible to select one to look at closer.

3. Often, but not always recording just stops.

I have the Setup CD but see no option to repair or update the camera. Are there any options?
