If you have applied a limited license and wish to remove it while still within your 30 day evaluation, you can do so by deleting the license file located here:

Vista:

C:\Users\[user]\AppData\Roaming\Kinetic Jump\AppLife Update\License.lic

XP:

C:\Documents and Settings\[user]\Application Data\Kinetic Jump\AppLife Update\License.lic

Once you delete this file and restart AppLife Update, all of the features of AppLife Update will be exposed again.
