Since you already hooked up a drier, and it has been on the car, you will need to replace the drier again. Like said earlier, the drier is the last thing to install, then the car needs to be connected to a vacuum pump immediately.
Did the replacement compressor have flat ports or stepped ports?

I thought what he meant was that he used compressed air to blow out the liquid flush material..and will be having a pro vacuum the system.
I totally agree that the drier needs to be put on new seconds before the vacuuming is to begin... it just sucks up moisture, has limited capacity, holds the moisture below oil and thus can not be renewed by vacuum as a result.. and once it gets full of what it can absorb then it can do no more...and your system is at risk of oil and moisture mixing and forming acid.
