Trialled DC Pro, bought DC Standard. Now it doesn't work because "the trial has expired"
I trialled DC Pro and set it as the default PDF program, but eventually purchased DC Standard instead. I have uninstalled DC Pro and reinstalled DC Standard. If I try to open a document, the tab in the top l.h. corner shows me that DC Pro opened it, even though DC Pro is no longer resident on the machine. If I try to print a PDF from, e.g. Word, I cannot because "the trial has expired" and Windows hangs. Clearly the problem arose because something in Windows still thinks that DC Pro is the default PDF program. So I have a piece of software that I have paid for which does not work. Help, please!
