180,000,000 credits and a free ship:
In order for this trick to work, you must own the original Starship Creator or the add-on pack. Create a shortcut on your desktop for either the original Starship Creator or the add-on pack, and then go into Starship Creator - Warp 2. Go to the fleet screen and click on "Import Ship". A window will appear. Click "Desktop" on that window to bring up a list of desktop icons that you have on your computer. Double click on either the original Starship Creator icon or the add-on pack icon. A message stating that too many errors have occurred will appear, and that it will shut down. Go back into the game, and check your fleet screen. You should have a Sovereign-class variant ship called the USS Insurrection. Decommission it, and you will get over 180 million credits. If you want the cash and the ship, repeat the process, but do not decommission the ship. If you get greedy and repeat this process three times and decommission all three ships, your credits will go down to zero.

Cheat Codes:

Cheat for unlimited credits:
Once you build your first ship, go to the "Fleet" screen, select the ship you just built then select "Export" on the command bar to the right. This will save your ship. Once your ship is saved make sure you are still on the "Fleet" screen. Make sure the ship you just saved is still selected, then cleck on "Remove Ship" from the right command bar. The computer will ask you to confirm the decomission of your ship. Click on "Confirm". This will remove your ship and return the credits(cR) you spent to build it. After you have been given the credits, go to the right command bar on the Fleet screen and select "Import Ship". Find the folder you saved you previous ship at (usualy its a folder named "Export" with in the directory you installed the game) and select the saved ship file (it should look similar to this: NCC12345) and click open. This will put the ship you saved back into your fleet list of ships. All you have to do now is select this ship again (on the "Fleet" screen) and choose "Remove ship" and confirm the decomission. The credits you spent making the ship will once again be added to your total credits. Just repeat this several times until you have 1,000,000- 2,000,000 credits. You can now put anything on your Starship that you want, and not have to worry about how many credits you spend.
