Moog Modular V Occasionally Requests Cd? Options

[nreyes]

I am using the Moog Modular V softsynth within my host sequencer, which I have duly authorised and registered with Arturia. However, from time to time it asks me for the CD?

Problem is, I tend to have to eject whatever is in my drive at the time, and then insert the original installation CD etc. which is becoming a pain in the ass.
Is this normal (e.g. software protection), or have I not authorised it properly?

There is nothing on the Arturia website about this.

I am awaiting a response from their Customer Support, but I was wondering if any other users have had this problem, or do I need an update?
