Wow. OK. First, we need to establish what version of Sampletank you are using. LE? SE? XL? Next, we need to know which platform; MAC or PC? Next, on the installation CD, there are installation instructions. If you followed them properly, then the sample library should already be installed. Next, the instrument needs to know where to look for the installed samples. You need to set the root directory for the samples (details in the next step). Last, the PDF manual gets installed by default with the software. It has detailed instructions in it on a). how to install the software properly, and b). how to use the software properly, including setting the root directory for the installed samples, and loading samples into the instrument. All of the steps I have mentioned here are covered in that document, as well as a whole lot more. I would definitely recommned spending some time with that document. It will definitely answer many of these very basic questions that you have, and put you on the right path to making music with this instrument.
