It works normally for me. try to re add your weapon binds. check /settings > Automatically shoot and aim > make sure its disabled.
I tried and tested it myself. I didn't got that message. But to be sure, I quickly used binds again and got the message. One of the main reasons for this is the game's restriction on bind speeds. Unfortunately, there's no solution to that.
No one else I know gets this message and I'm pretty sure everyone is using binds in LV. I tried it even slower and still got the same message :
If you're using a support program that hasn't banned from the game yet, or if you've made a bind that most people don't know, it's normal to take that message. Or if you're using macro in some way, you'll get that message. Personally, I played at LV for about 3.5/4 years and I didn't have a problem even though I'm using the binds faster than you. You can reset your LV settings and binds and try to do it again.
