Nothing but troubles with 4.1

Please make it possible to downgrade Rekordbox ta an earlier version.

Had Rekordbox 4.08 working like a dream on a quad core intel 2.4 ghz with 4gb od memory.

Then the upgrade 4.1 came along from that moment on it freezes after half an hour, sync does the strangest things, soundquality it cracks and quirks, an is overall unstable. I really regret the upgrade and I start to have regrets that i bought the RX because with a SX i could go back to Traktor or Serato
