Due to the technical improvements which we made in a new version, the old version of secret disk is incompatible with a new one. That's why switching to a new version may be easy not for all users. Below are few steps that will make the process easier for you.
If you already have new version installed, then open it. On the main screen of new version, at the bottom, click the link "old version is here".
The app may ask you if you want to start new version - answer "No".
That's all, you are back in the old version! Open secret disk using it, and move your files from the secret disk to your Desktop. Then, close secret disk and forget about old version.
Again, open new secret disk and start using it by moving your secret files from the Desktop to it.
