    Do not use this software. After installing, my USB printer will not function. After un-installing, no USB devices will work, not even in safe mode. In the middle of recovery now.

    As with any program, your mileage may vary, but I'd stay away.

    I almost forgot to see free betas... and 90 days seems to be infinity. Good amount of features for the very first version. Very nice and promising product!
