Script version

Hello everyone.

I'm a new kid on the block and was just scanning the forum for some answers, but now I have eve more questions, Lol.

Not sure if I'm asking at the right place here but if not, don't just delete me for making a mistake, please, it's just that I try to get used to the forum. Thank you.

Well, I run a free maian cart script and my version check says I run the latest version, which is 1.3. Somewhere in this forum (before I registered) I read that someone is running on version 3! Is there a difference between commercial and free version because 1.3 to 3, that seems rather a huge difference to me.

If it is, where can I find out what I'm actually missing by running such an older version as a free version?

Thank you.
