Restoring root privelages to an application.

[tt7]

I started wireless teather for the first time on my evo (fully rooted with 2.2 rom etc...) When the application started I accidentally hit "deny" while the "remember my choice" checkbox was checked as the app asked for root privelages. Is there any way to restore those root privelages to the app w/o re-installing wifi teather, as this specific version is not on the market?
