Hi, I just got a desperate call from my Brother. He said his current subscription of Retunil Pro is running out in a week or so, so he bought a renewal via paypal. When he tried to install, he says it tells him the old version has to be removed first. So he tried to uninstall via Add/Remove and it won't uninstall. When he clicks uninstall it just blinks. So he can't uninstall the old and he can't install the new. Does anyone have an idea what's wrong? Thanks in advance for any response.
