Installation destination issues

I am using a Dell Laptop and Windows 8.1 with Adobe Digital Editions 4.5.2.  The storage location where all of my epubs are saved needed to change due to the hardware wearing out.  The path to the new storage location is different from the old and I cannot change the path to match due to system limits.  When I try to install a newly purchased epub, it tries to save it to the non-existent old storage location and errors out.

I have tried uninstalling clearing and redoing my authorization for the computer, uninstalling the program and reinstalling it, and deleting out any files that reference the old storage location, but the problem persists.  Is there any way to change the default location where Digital Editions tries to save the file?
