Hi colbygray,
This issue is usually caused by not launching your Metatrader terminal with Tickstory (by pressing F8). Please re-generate your MT4 export and ensure you launch via Tickstory before commencing your back-test. A more detailed description of the back-testing steps is in the help manual (press F1 from Tickstory). There is also a trouble-shooting section that may assist.
Regards.
