[Solved] Rubberband Timestretch Tool Not Working

Hi,
I don’t know when and why but someday (after one of the Renoise or system upgrades) timestretch tool stopped working. Whatever I wanna do it gives me “Sample import failed with the error: ‘Unsupported file format or corrupt file!’”
Any ideas how to fix it?

I’m using Arch Linux.

OK, solved. There is problem with latest (1.6) Rubberband under Arch. Downgrading to 1.5 (it’s in AUR) helps.
