Normally the reg key looks like:
(This is NOT an actual key, sorry)
Make the following actions:
1. Copy this paragraph of text from your e-mail to clipboard (Normally use Crtl-C)
2. In AGA, click Help->Register to open the ‘Registration' window.
3. Use "Paste" button to paste reg key from clipboard.
4. Click "Register" button.
5. Small window will appear with congratulations of your registration. Click "OK" button.
6. Close and start AGA again.
When you restart the program, the information about trial period will no longer be displayed and the ‘About' window will show that the program is registered to your name.
If it does not work, make sure that you correctly copied the key to clipboard and then pasted it.
