Hi

I can no longer access my laptop from my PC. Everything was fine the last time I tried but now I can access my PC from my Laptop but cannot access my laptop from my PC. My PC is running Win Vista Business and all the updates etc. have been done. My Laptop is running Win 7 Home Premium. Vista tries to install a driver for the bluetooth connection but fails or asks me for a disk for the bluetooth device for which there isn't a disk! Any ideas?

Regards

Ray
