unfortunately EU 3.10 does not accept
I tried to do a downgrade with this soft but it does not work

someone will tell me how to do it

[jimbojambojumbo]

i had similar issue and i had to downgrade to 3.08 first there is a line that needs modifying in the autoinstall file it did fail to roll back which i worked out was failing on a file either the 5th 6th or 7th but you will see on screen which just keep looking at the screen then remove that file from the autoinstall file and it will roll back then you can do the update to 3.10 . I have put the lines in bold that i changed to allow it to roll back

Hello
Can anyone help me with this error?
I downgraded to sync 2 from v3.10 to v.3.08 and I can't do anything in the soundboard.
I tried to do a sound test from the test menu and it doesn't do anything. A help if someone has suffered from such a thing
