May I make two suggestions at this point:
After purchasing the upgrade, you can download the files with Cakewalk command center.
1st) It might be useful to have the size of the files being displayed somewhere, so you can estimate how long the download will take. (In my region, bandwidth of available internet access is maximally 16,000 kBit/s.)
2nd) Being forced to interrupt download, you will notice that when resuming it another time, you will not start exactly at the point where you have stopped. Only completely downloaded files will be kept, within a file there is no resuming of download after interruption. It would be great to change Command Center's programming in a way that it allows full resuming of an interrupted download.
