And to kill all those thinking about the "they have no internet!"-issues, they do. If they didn't have internet, how would they be able to download the game in the first place?
"But their internet is too bad!"
Have the trial version attempt to call the database once every new day it's opened to see if it's expired. Make a screen that checks, and if it verifies that it can be played, move on to the game.
If the person does not have internet at the time it's launched, you should have Game Maker create a back-up log file that displays the date and time first launched, then check that file.
"Why check the text file last?"
Because that can easily be manipulated. So to prevent that, we check the log file only if internet connection failed.
Or, if you're way out there, you can create a C# database and store stuff in that instead. But I wouldn't recommend that. At all.

And replying to a topic that dies many months ago is smart?
and if they have a computter without the internet? then they would be able to use it forever...not smart
Anyway, it's using the system time as a fallback. If they wanted to use it forever, they would need to continuously change their system time. It would be so time consuming, you'd be better off just buying it.

I made it 100% using Game Maker, and it's not using *.dll
