I believe your purchase is being held up for a fraud check. This would be to protect you. Although your bank shows a payment successfully made the funds are held until the fraud check can be made.
This will require a Stardock employee to check and complete the transaction. Unfortunately, Stardock office is closed until Monday morning.
Sorry for any inconvenience this has caused you.
I would suggest you email support@stardock.com and initiate a trouble ticket. Post the auto-generated ticket number here.
On Monday morning I will endeavour to make support aware of this.
