"If you already have the original version of My Digital Studio and want to give the MDS 2 Trial a shot, there are some tricks to installing it depending on your situation. In a nutshell, it makes things easiest to make sure to buy the software before the 30-day trial period is over."
More explanation is given in this post on www.mydigital studio.net:
If you don't own the original version of My Digital Studio and are just starting with the trial version or new MDS Version 2, then I don't think any of this applies to you!
