Random Error Being Thrown

I am unsure of how I could of fixed on the model that was originally referenced in this question. What I did after experiencing this problem and not having any luck with the adivice I was given was try to use one of my compay's already existing datasets with similar data. This went well until I started getting thrown errors again, this time when I uploaded my data to Service. If you check my profile you'll see another post that occurred about a week after this one about this. So I followed the advice that was given in that post and deleted the data that was originally in the data set so that I could switch to Import storage and the reupload the data that had to be deleted. I wasn't too sure whther this would work since the date data table and many others that were giving me problems from when I posted this post would have to uploaded again, but it did. I know this likely won't help many situations, but if you're in a similar situation don't be afraid to save what you have and work on a copy of your work or restart and try different storage modes to see if your issue persists. Also, don't be afraid to post on here often. Everyone is so hknowledgable, helpful, and willing to look your way.
