Phase/Capture One seems VERY fussy on its software security, they have set it to think that anything changing on your system = attempted fraud, and de-activate it.
This level of 'security' might be ok for the normal person with a one unchanging desktop, but photographers are not like that - we are always plugging in high capacity CF cards (64Gb, 128Gb) memory sticks, (I have 128gb and 64gb USB3), extra hard drives and backup externals come and go all the time. Its part of our process. Duh.
But... if you install C1 with any of these on there, like a 64Gb USB stick, it will think it smells a rat if its *not* there the next time it starts, and de-activates itself, or switch you to trial mode. Its extremely annoying and really smart of Phase - they should look at this more reasonably, given their clientele, and lower the 'system changes' security settings.
David - Yes I requested support, and got it, but they just suggest the usual deactivate and re-activate routine. Its a silly and annoying hiccup for a minor release update. I would recommend people avoid it.
