First, you should check pricing again as for me & @Quesito in Spain:
1./ 2x eMC Pro Licenses is €29.98 to total €59.95
2./ 2x eMC Business Pro Licenses is €34.48 to total €68.95
The only listed difference between them is License Manager with Business Pro - not really necessary with only 2 Licences
Perhaps you would be better advised to purchase Lifetime upgrade.
As @Quesito says, even if you are expecting problems you only need to consider €7.95/yr VIP extension cost
