In these last few days I have read a lot of posts from users concerning the new version. A good many were about how there is no longer a delete demo option. I also miss this feature. However, there is a way to circumvent this. Here is how I have resolved the 'problem'.

WARNING! This solution requires you to physically delete folders. It's not hard though.

1.) Load the program. Virtuagirl HD (VG) and/or Desktop Babes (DB).
2.) Make a quick list of the card numbers, including weather they are VG or DB cards, you no longer want.
3.) Under the Settings\Advanced tab in the 'Downloads' section make sure all four boxes are unchecked. These are the two auto download options, download after quitting and the P2P option.
4.) Make sure no files are being downloaded. If there is, let them finish. I'll wait.
5.) All done downloading? Alright, close the program completely.
6.) Go to the 'models' folder inside of the vghd folder. It's usually, c:\Users\YOUR_USERNAME\AppData\Local\vghd\ or close to that. You could also search for a folder name vghd.
7.) Remember the list from part 2? Get it out.

First a legend of the folders you will be looking at.
A = Virtuagirl
C = Desktop Babes
The four digits afterwards are the card number.
EX. A0305, C0047, A0486, C0156. These are what kind of names you will see on the folders.
Lets say you have a VG demo you want don't want. We'll say it's Elya / Sporty Day which is card number 22. The folder name will be A0022. Delete it along with the other cards you don't want.

8.) Load the program again and you should see the demos are now gone and are no longer a playable option.
**NOTE**
I have noticed the girl(s) may still remain in color as opposed to the monochromatic color of the non-downloaded girls but if you click on them it will play a downloaded card instead. Seems to just be a bug in how fast the program updates its library.

Hope this helps.
