Prices for ADM upgrades are found at www.aseba.org > Catalog.
To upgrade to ASEBA-PC from ADM, go to www.aseba.org > Online Store or print an order form from www.aseba.org.
You will be required to provide your current serial number(s) to be eligible for the upgrade prices. Your serial numbers are on stickers on the CD covers.
If you can't find the disks or the covers:
