Welcome to LMMS,
Is this a new install of LMMS, and it's your first time running it?, or did it run OK before and just start happening?
first time i've used/installed LMMS, ive tried running it multiple times but it always shows that same screen.
please post your:
* OSservice-pack-ver
* lmms vers
* hardware specification (ram & soundcard is the most imortant)
* lmms sound device chosen
@alekb this is a known issue with the portaudio driver on specific systems.
