Traktor SP2 issues

hello

ive recently switched from serato to traktor, and im finding the transition rather over whelming...

i use vinyl and external mixer ( djm800 )....

so i recently figured out how to allow the software to let me do the loop recorder... i had to make channel D set as FX send/return, so then i can only drop sample loops into channel C, which means i lose 4 loop banks in channel D... this is frustrating to say the least, but its better than not having any loops what so ever... but if anybody can tell me a way i can get around this so i can have both channel C and D as loop banks that would be great...

next issue.... i cant get the software to recognize my mixer or vinyl anymore... and no its not a mixer issue.... i plugged serato up and bang works fine, and can play normal vinyl through it no problems....

why has this happened.... i managed to get the loop issue set up, had a little play, then turned off the software, came back later, turned it on... and bang nothing, straight flat line.....

can somebody please shed some light on this

thanks
