Hi, when downloading there is a choice to download multiple files but if you do this they do not unzip properly…that was the first problem, so had to re download one at a time…took a while did that!, then, if you move the unzipped files to an internal disc other than your C drive and …again they will not unzip properly, they have to be unzipped on your C drive, strangely non of this info is on the download page, anyway after very good support from IK I got it sorted…
