Narrative:

I was given taxi instructions from the FBO to runway 30L. Original instructions were to taxi to runway 30L via taxiway F and to hold at taxiway K. These were then modified to hold short at taxiway J with which I complied. After the airliner passed; I was cleared to runway 30L hold short of runway 30R on taxiway J. As I reached taxiway J; I was cleared to cross runway 30R and turn on taxiway D to runway 30L. I crossed runway 30R and proceeded to taxiway D. As I approached runway 30L I was told to hold short. I stopped immediately. I was again told too hold short and I again told ground that I was holding short. I was then told to cross runway 30L and turn on taxiway C. I asked if I should turn on taxiway C instead of taxiway D and they told me to turn on taxiway D. I then departed from runway 30L. I was asked to call the tower while en route home. Upon arrival; I called the tower and was told there was to be an investigation for a runway incursion. A jet had to abort because I was crossing runway 30L. I told them I was cleared to runway 30L and was proceeding as instructed when I was stopped. They said on the tape I was instructed to turn on taxiway east not taxiway D and I had repeated those instructions.
