I don't fully understand the symptoms you describe, but:
Those 10 turn pots can have funny pinouts. ?I'd take it out of the circuit, check with an ohmmeter. ?Make sure you have identified the correct middle pin. ?And check with an ohmmeter to determine if pot is more or less linear (though I doubt there's many 10 turn pots out there that are logarithmic). ? If you did have it wired up wrong with either 5v or GND on the middle pot pin, you could have damaged the pot as current would get very high when resistance between 5v and GND nears zero.

But I noticed something weird. When I turn pot max or min there is no more quick change of freq. Pot behaves pretty strange, I feel that it is changing non-linear, with extremely high values at the beginning (or at the end).
