Default EveryTrail won't upload tracks

I know it's a long shot, but I thought I'd reach out and ask if anyone knows how to get GPX files off the Android EveryTrail app. I cannot get them to upload for some reason. Running ET 3.8.8 on a rooted Samsung S4 Active (4.4.2). I'm pretty sure the issue is on the ET side and not on the phone. I continually get a "Connection Error: Please try again later". I figured the files must be stored somewhere on the device, but I cannot find them!

Any help would be great!
