Modem or SIM not inserted - Medion 3g USB STICK

[Harderro]

Hello, 

I bought a usb-stick every time when i restart my laptop it stops working. 

Even if i switch computer to sleep its saying - Modem or SIM not inserted. 

Changing usb and reinstalling medion software didnt helped.

After reinstaling software everythings fine i play games on gameranger but when i switch off pc its not working again.

Any suggestions?
Thanks.

They gave me this link for software:

hi @Harderro 

I am having trouble identifying the product in question, could you kindly post the MSN number (8digit) and maybe a picture or two of the stick's labels.

Many thx
