Both versions 2 and 3.5

Hello, this is because you did not uninstall version 2 first.
Please quit the current version using the padlock of version 3, then rename the Espionage to Espionage3 for example, download the version 2 from www.taoeffect.com, launch it, select uninstall option from Espionage menu, this will decrypt all protected folders and remove all traces from version 2. Then you can rename the Espionage3 back to espionage and start to use it.

let me know if you get stuck.
