.3GP file not playing in Shotcut

I am quite new to learning how to make a simple basic video, but am thrilled to have run across Shotcut. Would like to know the best way to get my .3GP video to play when I open it up in Shotcut. I have looked at most all the basic tutorials that show how to open up the program and bring in video/audio. I have also read ALL the FAQs, tried a few little things, but unable to get my video to play. There are a few converters out there but would prefer to use one that you recommend. Please see specs below, and thanks again for Shotcut!

OS: Windows 8.1
64 Bit
2 GB
Windows Media Player 10 (installed)

It appears your computer is severely short on Memory.

.3gp is old phone footage, does it play in VLC? If not it’s possible the file is corrupt.
