Couldn't read filearchive because of a fatal system error

Hi there.

I decided to try out your software.
I installed it on my mac OSX 10.10.3. When I start the software & click ‘start pro demo’
I get this message "Couldn’t read filearchive because of a fatal system error (#001) Contact support.
Obviously this isn’t normal. Can you assist me?
Thanks in advance.

Regards Ace

Anyone??
