AT GON ON THE RAMP -- NIGHT. AFTER STARTUP AND TAXI CLRNC TO RWY 23. STARTED TAXI LOST MY POS AND ACCIDENTALLY TAXIED ACROSS RWY 23. TWR CAME ON AND SAID...YOU JUST CROSSED RWY 23 DO I WANT RWY 33 -- CONTINUED STRAIGHT AHEAD. I REPLIED OK 33 IS GOOD; AND CONTINUED TO AND STOPPED AT HOLD LINE FOR 33. TWR CAME ON AND SAID CONTINUED STRAIGHT AHEAD. I TAXIED TO 33 CTRLINE. NOW TWR CAME ON AND SAID 'YOU CROSSED RWY 23 WITHOUT MY PERMISSION; NOW YOU TAXIED IN PLACE. AGAIN; YOU DID NOT GET MY PERMISSION. I SAID I'M SORRY. I WAS DISORIENTED BACK THERE AND THANKED HIM FOR HIS HELP TO RWY 33. HE CLRED ME FOR TKOF. I AM AN ATP PROFESSIONAL. I HAVE NEVER HAD TROUBLE TAXIING AT THIS ARPT AT NIGHT. THE PROB STARTED WHEN I LOOKED FOR A LIGHTED TXWY TO LEAD ME TO RWY 23 (VERY DARK NIGHT SKY). THE ONLY BLUE TAXI LIGHTS I FOUND TOOK ME OUT AND ON RWY 23. I QUICKLY CROSSED OVER WHEN TWR CALLED AND HAD ME CONTINUE TO RWY 33. WHEN I HELD AT HOLD TWR HAD ME CONTINUE TAXI STRAIGHT AHEAD; AND I ASKED DO YOU WANT ME IN POS ON RWY 33? SO; TO SUM IT UP; I WILL STOP AND ASK FOR HELP WHEN I DO NOT KNOW OR HAVE A QUESTION DURING TAXI. I WILL NOT CONTINUE TO TAXI WITHOUT A CLRNC. I AM A VERY CONCERNED PLT AND I WILL NOT REPEAT THIS SCENARIO AGAIN. AT THE TIME OF THIS INCIDENT; ONE TWR PERSONNEL WORKING TFC AND GND. NO ACFT TAXIING -- LNDG OR DEPARTING -- OTHER THAN MY OWN. THE ARPT WAS KNOWN TO ME NIGHT AND DAY. NO PRIOR PROB TO FIND MY WAY AROUND. I HAVE LEARNED WHAT NOT TO DO FROM THIS.
