DaJeep dude, turn the ignition off and relax, you may be trying to run an exe in your TP. Run from your PC/Laptop and install in your TP. Or do you have a cab? I use.91 and it is an exe that I have. Leme know, we ll get it to work, no worries....also, Sktool has a feature to disable TP from asking for certificate,however you rolly dont need it.
