Why doesn’t Toshiba Video Player in my laptop playanything.

Hi, I had this laptop for several years. The video playerthat came with it used to work perfectly. About a year ago it quit playing sometype of videos, but it still played mostof them. A week ago I had my laptop reset, and when I got it back, the playerwould not play anything. I put in the new update, and still nothing. I did all the other updates, except the onesthat were supposed be done before installing Windows 8.1 to Windows 8, since Ialready had Windows 8.1 installed.

When I click it, the player pops up, I get the announcementabout 3 D, and the name display comes on. Some things light up on the top andbottom line, the rest are all faded. When I click the settings, I see the playbutton, but it doesn’t do anything when I click it. I have tried with various DVD's, but nothing works.

I am not sure what version I had before having it reset,but when I got it back it had: and I updated it to thatincluded a patch.

Windows 8.1
Toshiba Laptop P845t-S4305
SN PSP 55U 008 002
Purchased in 2012, but in top condition

Any suggestions anybody?
