PP7 Calendar - Change Month?

I have just installed Page Plus 7 on my computer - solely for the purpose of raising a calendar sheet.
I have used the wizard but after the basic page is chosen and set I can find no way of changing the month from that which defaults with the wizard.
I have tried inserting another "calendar" from the insert but that gives me choices which are not the same as my chosen scheme via the wizard.
At first I thought that this was a wonderful piece of software but now after an hour of pure frustration (and the "help" file is useless for this problem) I am of the opinion that it's total rubbish for the use that I required it.
I am hoping against hope that someone has a simple solution.
