I have tried both wamp server 2.2 (with multiple install attempts) and the 2.3 beta.
With each install attempt with both versions all the services started initially (on first launch) no prob but then after either "restarting all services" or shutting down wamp and re-launching results in mySQL refusing to start.
Restarting my machine was also of no help.
Googling around has not provided me any insight as to the cause of the problem or a point to start looking to solve the prob.
Any assistance would be fantastic.
