Can't access EMS Access Encrypted Files on USB drive

I had a USB drive that had files on it that were encrypted, and in the root directory was the file "AccessEncryptedFiles.exe".  

File description is "EMS Access Encrypted Files Redirector."

Version: 8.11.0.24

I copied the files from the old USB to a new drive with more space, and now when I try to run AccessEncryptedFiles, nothing happens.

Previously, it would run and ask for my password.  Now, nothing.  So I can't access my files.

HELP!
