Using Whatsapp (BlueStacks) on two computers?

[Jan_3_]

Hi! Since I don't have a smartphone, I used to use Whatsapp on my iMac via BlueStacks. Now I'm living abroad and didn't take my iMac with me, only my Windows 7 Laptop and I need WhatsApp to read messages, but it doesn't work:

I installed BlueStacks and WhatsApp successfully and connected it with mobile phone number. When I opened WhatsApp, there were no contacts and no messages!

How can I fix that?

I'd be glad about some help!
