Hi, I need tech support help please. Impossible to find any tech support email…..

 

The issue;

I bought a BlackWidow V4 and when the computer start all keys are light up and working fine.

But as soon as Synapse 4 load a profile this key # and key < not light up any more stay black.

In Synapse 4 you cannot even change any things on this 2 keys. Synapse show blank keys.

 

I try all things i could find on the web, reinstall everythings, hard reset,… I try it all.

Is there anyway to fix this issue? I found on the web many people as the same issue but not fix found.

 

Please tech support need your help
