It was paid but fairly cheap if I remember. I've been using it for a couple of years now.
I downloaded a trial version of the software you referenced to get a better idea of what it offers.
(Without payment, the trial version only permits "encrypting" and "decrypting" once along with "disguising" and "undisguising" once.)
You mentioned your files had used the "encrypt and hide" mode so that is what I initially experimented with. I also tried the "encrypt with fast encryption" mode to compare results.
Good news: I believe your files are easily recoverable, even without a password.
Bad news: The software you're using to encrypt data doesn't seem to encrypt ANYTHING *at all*. It merely moves the files/directories you select for encryption/hiding to a location that is not viewable by simplistic file managers (e.g. Windows Explorer) or the bulk of common application software.
I suspect the following will enable you to access your "encrypted" and hidden files:
1) Make note of the drive letter that Windows currently has assigned to the disk containing your "encrypted" and hidden files.
(You stated this previously was D:, but it is possible it may have changed after reloading Windows. I'll use D: in instructions below, but beware that it could be E: or F: or something else...)
2) Identify or create a folder where you want your your "decrypted" files placed; e.g. D:\MyFiles
(The "encryption" software seems to keep files on the same drive they originally existed on. If you want them on another drive, like C:\MyFiles, that works too)
3) Install 7zip, if you don't already have it installed. Once installed, launch 7-zip File Manager.
4) In 7zip File Manager, by default you'll probably see a listing of your C: drive. Highlight the "C:\" at the top of the listing and change it ot "D:\" and press Enter.
5) Navigate to D:\RECYCLER.BIN1\MICROSOFT-7701091-6666888-16826688....\$$$\com8.{21EC2020-3AEA-1069-A2DD-08002B30309D}..\
6) You should now be looking at a folder named "local" which contains all of the folders and files (residing on your prior D: drive) which you previously "encrypted" or "encrypted+hid". To access them, you first need to move them to a simple path that most software will understand. You can select the "local" folder and Press F6 (or click the Move icon at the top). You'll be prompted to specify where to move the data; Enter (for example): D:\MyFiles Click OK and the files should be moved to D:\MyFiles.
7) Now you should be able to browse to D:\MyFiles using whatever software you usually use to access your documents.
Good luck!
