Today I was Fly From LIRF (Rome) to LIMF (Turin).My FP: LIRF - GILIO - ELB - GEN - TOP. FL240.When I overfly GEN VOR, Milan Control declare a vector control and assign me HEADING 120 (Back Track).After 5 minutes assign to me Heading 330. This situation for two times.Why that? Where I wrong?

were you 40 miles from LIMF? did you miss your crossing restrictionof did you miss your checkpoint?what did the rc menu say your next checkpoint was?jd
