Bought used from thrift store

Well i bought a ION Discover DJ used from my local thrift store, was no CD or CD/Registery key with it, was working fine up tilll bout an hour ago and it just stopd working, all the lights lit up but the left REV button, when i started up the mixvibes program. Is there any way to fix this and anyway to get a registery key?
Also was wondering is this compatble with Abelton Live 8?
