Dianne, one thing to make sure. If you get prompted to update with patch #3 you will run into issues with some (many) scripts. You will have to install the Python module package (it might be missing from the version you downloaded). If so, it is easy. Download it here:
then, execute it. It will fix it all.
As for the gradient fill tool, yes, it is a new feature of X9 so don’t look for it in X8.
