Pdf creator problem

Had it installed for a long time and it said my trial version was over.

I downloaded it again and it still says the same thing.

It asks me if I want to buy it.

Is the new version infected?

I can't use it at all.

 plase be sure you product is really pdfcreator from sourceforge,
there is other products named equal or similar.

uninstall the product and install from here:

also please be more clear in the subject when post "I have a problem" is not a descriptive title.
