check for sharp/scuffed edges on bridge pieces or nut (you may have caused damage during adjustment) check your string gauges (try a set of standard 9's or 10's) check your trem tension (adjusting the screws holding the spring anchor in position) check your tuning (are you going an octave too high?)
Can I tune down a Floyd Rose?
Can You Change Tuning on a Floyd Rose? You can change tuning on a Floyd Rose, but it is more complicated than a standard guitar. Changing tuning will change the tension in the strings, which means you need to rebalance the tension for the Floyd Rose to stay in tune.
