I have gone and signed up for the trial of pixinsight. which I must say looks really good. But a big learning curve in that one.
This issue with DSS has done my head in for the last week and I think I have to admit defeat. (I'd rather be out taking pics than fighting with software).
I will just have to stack on another computer for the mean time. Hopefully DSS will bring out another update soon and my problem is resolved.
Thanks for all the help and suggestions guys. Much appreciated.
