Lic.Key invalid on PhotoPresenter 3

I know there is an update to PhotoPresenter 4 BUT I do not want to use it. I’m quite content in using the older version for my presentations. What can I do when the software does not allow me to insert the old or new password. I also have PhotoPresenter 4 but not on this computer.

Please contact as we need to take a look at your licenses to fully understand what you mean.
