HELP! Cannot see/load Images, Audio, or video in project

After searching through other posts, I cannot find out what happened or how to fix my issue. I downloaded a trial version to determine if this would be a good program for our company, but already ran into major issues. 

Project details: 

3 Scenes: Scene 1 has 12 slides, scene 2 has 6 question slides, scene 3 has 7 question slides

Windows XP, working off of local hard drive the entire time, all images/video are on local hard drive and verified they work. 

Issues:

When looking at Story View (see image below), all images are visible and look great, but when I open one of the slides, the audio isn't loading, images won't load, and the mp4 videos won't play (see image below). HOWEVER, on the first 9 slides of the first scene, everything works perfectly including the audio, images, and video. 

1. "Loading Audio..." appears on multiple slides and never loads. However, some slides have multiple audio recordings and one works fine, but the other one just says loading audio. I have let sit for an hour and nothing... Is there a way to find source audio file recording? Note* I can delete the audio and record new within this project and it seems to work. 

2. Images: Won't show on slide view. I've tried deleting image and re-inserting, but that just gives a blank image box. (I did find that creating a new Storyline project and inserting image works fine, but I don't want to redo all my slides). 

3. Video: Same issue with images. 

I like this program, but being this happened the very first time of using the program that is a big turn off. Any help is appreciated! 

Thanks,

Dave
