RStone IS a macro. You need to get the activation code from the author...I believe information on how to do that is in a PDF on the same site from where you downloaded rStone.
Since I am new too, and wondered if I would have the same question, I went on a hunt for the answer. This seems to be it:
"Choose a system carefully, since this locks to a system permanently, and is never transferable to another other system.
Final install keys are only created when you follow the instructions and send us your code found in the macro. Allow 1-48 hours after you've done that.
NOTE: This macro will only run on one machine. This means if you buy the macro now, and want to run it on a brand new machine or a different machine after receiving your first activation code, you must buy it again. Think carefully about which system you want to run it on before sending us your system code. Activation data is based primarily on serial number of your system's logical Hard Drive "C:\". Any manipulation with this disk (Formatting, or physical replacement) will lead to lost activation, requiring you to make a new purchase."
Please remember that this Macro is $50 and compared to the many other rhinestone software programs out there costing upwards of 1,000's of dollars.Yes, that is a BIG drawback to rStones. Locking to the system permanently....no matter what and having to repurchase even in the case of hard drive failure or similar unpredictable computer snafus.
