If your having difficulty with the basic unlock procedure/instruction that you received with your unlock key please read these more in depth instructions;
Run the trial version of the game you purchased from its desktop icon or start menu group.
You should see a "Silver Creek Entertainment Presents" screen. The screen will then indicate it is running the trial version and move to the "HardwoodGames.Com" advertisement screen. You should see options for "Play Full Version" and "Play Trial Version" as well as advertisements for our other games. Don't choose any of those options, but do the following instead.
There should be several keys on the top of your keyboard labeled F1 through F12. Press the F6 key (not the individual "F" key followed by the individual "6" key) located in the center of those. This will bring you to an unlock screen. Enter your name in the "Name" field EXACTLY as it was emailed or shows on your label. Then enter your unlock key numbers in the "Key" field. Your unlock code should be 3 sets of 4 numbers (xxxx-xxxx-xxxx-) for Hardwood Spades, Hearts, and Euchre. Your key will be 4 sets of 4 numbers (xxxx-xxxx-xxxx-xxxx-) for Hardwood Solitaire III, Hardwood Backgammon, and Ruckus Bucks Dangerous Mines. It is ok that there is a dash at the end of the last number. That dash is supposed to be there.
Now at this point you will have some different options depending on the game your unlocking. If your unlocking Hardwood Spades, Hearts, or Euchre there will be only one button to choose. Press the "Unlock" button and the program will thank your purchase and ask you to restart. Press the "Restart" button and your all done.
If your unlocking Hardwood Solitaire III, Hardwood Backgammon, or Ruckus Bucks Dangerous Mines there will actually be 3 different buttons. Before we go any further, if you aren't already, you need to connect to the internet. Once thats done, go ahead and press the "Unlock Via Internet" button. A box with some animated gears turning will appear. You will see "retrieving data" and then a box will appear saying "Thank you for purchasing" and have options to "Restart" or "Exit". Press the "Restart" button and the game will close and then restart.
Congratulations, your full version is installed.
