Video Not Playing Right

Hi all.
I created a project about six months ago and started working on it. I was almost finished with it, but was told by my company to put that project on hold because a different project needed to take priority. It has been about two months now and I am ready to go back to the original project. I open the library and find the project I want. It seems to slowly load, but now when I press play, the video will play for about a half second, then freeze, but the audio continues on. I obviously can't edit like this, but I am at a loss on how to fix this issue. Any ideas?

Thanks

Never mind, it was a hard drive issue. I have resolved it.
