Uninstalling AudioLabel will not delete any of your saved label design files. All of your saved label files have the ".aud" file extension at the end of the file name, and are not touched when uninstalling.
However, uninstalling AudioLabel will remove any printer settings, custom dimensions in "Edit Dimensions", and any changes to the default templates that load when AudioLabel starts.
I did a search for your error code, but could not find it in AudioLabel Version 5.0. (maybe you are using a different version).
If you still have problems:
1. What version of AudioLabel are you using?
2. What operating system are you using?
