But let me say one more thing: Suda software is constantly changed every year because of the channel policy, but you just need to confirm that the Suda software you bought is genuine.
You call the manufacturer, but the manufacturer can't get through. You have to have a VIP card, which means that no matter where you buy software, you only need a VIP card.
When calling the manufacturer, score the sales phone number of the company or Guangzhou Suda, and don't call the vip service number.
