Rocksmith Toolkit error

[NoPromises]

When creating custom track using the creator I get an error.

Please help, I plan on creating the whole of the Incubus discography for RS2014.

well it's beacuse ou haveno wine translator for windows exe files, It required for ddc\ww2ogg\nvdxt\revorb\topng.exe files, in future we'll switch to .NET implementation for nvdxt lib and one day for ww2ogg+revorb, but topng(Inlays) and ddc still would be exe files, someone metioned that we may have bug with paths handling at mac but I'm sure we haven't :)

Update your toolkit to beta for new features and bugfixes we've got there.

The beta worked. Thank you for your help.
