Crack permanently IDM

My IDM had been expired a long time, and I didn't know which version of IDM installed on my laptop to google the correct serial number. However, I have got a method to solve this problem regardless which version of IDM using. Here it is:
- copy the following code below to C:\Windows\System32\drivers\etc\hosts

127.0.0.1 tonec.com
127.0.0.1 www.tonec.com
127.0.0.1 registeridm.com
127.0.0.1 www.registeridm.com
127.0.0.1 secure.registeridm.com
127.0.0.1 internetdownloadmanager.com
127.0.0.1 www.internetdownloadmanager.com
127.0.0.1 secure.internetdownloadmanager.com
127.0.0.1 mirror.internetdownloadmanager.com
127.0.0.1 mirror2.internetdownloadmanager.com
127.0.0.1 mirror3.internetdownloadmanager.com

 - after that, open IDM and fill one of the key below:

QIBWH-F5SRH-9XAM2-DVHDR
or
L59BR-8CKUC-W9RIM-YSOT6
or
MWNDP-HO0R0-0U710-I63WG

 Hope you get thing done.
