Reply to Need Help!!! Kontrol S4 + MF Problem

Hi, so i recently added a MF Classic to my setup, i was using the Ifighter mapping in my gigs but i wanted the button feel!!! So last evening i had a gig and i setup everything as usual and started playing and all of the sudden doing a MF Combo Traktor just crashed!!!! 150 people where buuuuuing me so i rebooted my MBP and in a minute started playing again mainly using my effects from the S4 and when everything started flowing i began to use the MF and pummmm Traktor crashed again!!!! it was the worst feeling ever, i even had to go with the place setup (cdj 100 mk3 djm 800) for the rest of the evening with some backups cds i always bring. What can be happening???

My setup is MBP 13 8gb ram, 256 SSD Traktor SP2, kontrol s4, and the MF

Pleaseeee help me!

Thanks in advance!!!
