All of a sudden Alan's Personal.xlsb workbook stopped loading whenever he started Excel. He has confirmed that it is not loading, although it has in the recent past. The workbook is in its correct location and he can open it directly—it just will not load automatically as it is supposed to.
There could be a couple of different causes for this problem. The first thing you want to do is check to see if the Personal workbook has somehow become disabled. Follow these steps:
Excel disables any add-ins that it thinks are corrupted in some way or that it believes won't work properly with Excel. While the above steps can temporarily make your Personal workbook active, it won't fix the problem in the long run—you need to replace the file with a backup that Excel doesn't think is corrupted. (If you don't have a backup, the you'll need to recreate your Personal workbook from scratch.)
It is also possible that the directory in which the Personal workbook is stored has somehow become "untrusted" to Excel. The workbook is created, by default, in a directory similar to the following:
You should understand that the actual directory may differ, depending on your version of Windows and which version of Excel you are using. This directory is supposed to be trusted by Excel as a repository of "OK to load" workbooks. If the directory is not trusted, then Excel won't load anything it contains.
You can check to see if the directory is trusted by following these steps:
Figure 1. The Trust Center dialog box.
At this point you should be able to look through the directories in the dialog box and find the one where the Personal workbook is stored. If you don't find it there, then you need to use the controls in the dialog box to add it.
