Sorry for my english, i'm french...
I just buy an amplifi tt and i'll try to install the latest version.
I well install line6 updater 1.10 and line6 driver 2 version 1.77. I'm on windows 10.
It says that version 2.50.2 is a success but all the light under the tone bouton (A B C D) flash ans it doesn't work. So i tried the update (power off; holding tone and tap bouton and power on, i heard the bip). B and c is lightin and it still doesn't work....
If i return to version 2.10 it works.
Do you have an idea to fix the problem ?
