We have for several years been using a custom script to help us lay out our books. It imports image and text files into labelled frames. But that's not really important. What is is that on one machine, I just can't get the script to load. I've done everything I can think of. The PC has registered and fully updated versions of CS5 and Windows 7, a brand new harddrive (which I thought was the problem so replaced to no avail). We have 5 machines identical and the other four function perfectly. I've run as admin too.
What happens is that you have the active document open, click on the script and it should open ready to use, but with this machine I always get the message 'Cannot connect to InDesign'.
