Hello Frank and everyone, Thank you for the replies.
As Daniel and many of you suggested I checked the file handles and it is the issue. I had forgotten about that as I was stepping through the software. We have to have a lot of files open at one time in order to provide for "quiltting" of the images. I was planning to optimize how we load the layers and now I have a good reason to move if from "plan" to the "todo" list. I think we can get away with around 100 open files and still cover the viewing area. I apologize for not making my explanation of what was happening clearer. When I said " If I manually open the files it says can not be found, it opens them without issue. " I left out the part about restarting the program and not using the "auto" load feature. When it gave me the file as not found, I restarted the program and manually opened the file. At that point I only had 1 dataset open so naturally it worked. Again, thank you all for your help!
