Missing DAT file

[magical46]

Hi, i have just copied all my synchrolight and show files to a laptop (so I can work on my shows without disturbing the wifes TV !!) all is working fine except in Show Designer when I highlight my RGB pixels section and right click then select "Patterns" I get an error message saying " .....\synchroLight\RGBPatternsLibrary.dat - File may be corrupt or missing" I am using an SD controller and can add my own sequences but not the patterns. If I use the PC where I originally installed everyting it all works fine and I can add patterns. Have I missed something in copying to the laptop?
Any help much appreciated.
