I've recently begun to get an intermittent error message when I try to register subs using CCDIS. It doesn't happen all the time. The message says: 'invalid - register or remove CCDInspector/CCDIS'. The 'Align All' button show a thin border and is unavailable. Needless to say, both CCDStack and the CCDIS plugh-in were bought and paid for some time ago. How can I sort this out please?

I believe you also have CCDInspector, is this correct?

If so, please try running CCDInspector and see if you get a similar error. If you do, please email me privately with your CCDInspector key and registered email, and I'll check it for you:
