I've been trying to tune my Dime to standard from Dropped C, it's never been any hastle before, but I've been sitting re-tuning, setting the floyd over & over again, it just won't stay in tune, the bridge just keeps going up.

Tuning isn't that easy with a floyd rose. You should have thought about that before getting a guitar with it.

Try using a lighter string gauge. And then just adjust the screws in the back.

I hope you weren't planning on making this change regularly
#4
The string gauge I use has been fine for standard at all other times.

I've adjusted the screws, then tuned, over & over again, no difference.
