I will not use iPreach for exactly this reason.  Period.  Which is sad, because Keynote is a very nice piece of software.<p>I had a combination of things happen where I installed an upgrade, and it effectively locked me out of my files.  I had to pay for a new Keynote version to get around the problem (I no longer remember all the details ... I think it had something to do with an iLife subscription vs. standalone and auto-upgrading my data file version).<p>I was <i>REALLY</i> pissed off.  And vowed I would never buy software again where I didn&#x27;t control the physical copy.
