Help with mac terminal to use a keygen please

Hi,
I download phpstorm with a keygen and the instructions for the keygen are as follows:
INSTALL NOTES:
|
| Open a Terminal
| chmod +x keygen
| ./keygen
I have opened a terminal and typed ‘chmod +x keygen’ but I just receive an error saying there is no file or directory.
Could anyone help me with this? I’m really despearte now as my trial has run out and the program keeps restarting itself every 30 mins.
Thanks

Answer #2
Thanks for the help…I did some research about changing the directory and eventually figured it out
