AGAIN REALLY!!! DO NOT TRUST THEIR UPDATES!!! Latest update makes it unusable again. Problems changing amps. Can no longer open some saved presets. One star only because I can't give a negative number. Was my favorite app. No longer considering desktop version. Will go back to old school real amp and pedals.

Sounded fantastic, but now crashes on startup

I love this. Sounded really authentic. I was considering the desktop version. But now it crashes on startup. JamUp, Bias, Amplitube, Mobile Pod still work. But this doesn't. Please fix it.

All fixed! Sounds better than ever. Keep up the great work.
