Hello guys,
I’m trying to upgrade my v4.4.2 copy to v6 but I can’t find my original serial number 
Any ideas are greatly appreciated!
I’m sure that if you email RealMac, they’ll be able to tell you from their records of the purchase.
All updated versions can be found here:
I emailed Realmac this morning and they responded with the information just a few hours later!
I was able to upgrade and download v6 already, thank you so much guys!!!
