I thought this was free, but got a notice of 1/2 off today. Is this legitimate?

Thanks.

There is probably a free version and a paid version.

There is a free version and a paid professional version.

Yes, they from time to time come up with "Special offers" to get you to buy the Paid version, just keep on Ignoring these offers unless you want to buy the paid version.. Personally I stick with the free version, not much difference from the Free to paid.

Thank you to all!

Yup... ignore.
