John on Ezdrummer tells me to locate sounds, but i have had no luck... please help

Just uninstalling and re-installing does not require a new Authorization, since the Computer ID does not change by that fact alone.
Looking at your account, you do not seem to have used another Auth, so I presume you just clicked Authorize and had the same Computer ID.
Anyways, you will not waste Authorizations, we're here to help.
