Is there a way to do this without contacting customer service?  I bought the $59.99 version just recently and I want to get the premium version, which costs a little more, so how would I do this? Do I download the Premium version, then install it, then enter my serial and info or whatever from the standard version, then be directed to a link where I can pay the additional cost?  Or what?

Thanks for any help!

I did a little more digging; it looks like I'll have to purchase the Premium version full price, different serial and everything... that's a shame... Can't I get a refund for the other version, I've had it less than 2 weeks, and now I realize I made a mistake.. Oh well...totally different product, I guess..
