Check if all the 6 services are running in computer managment. If the PBX status is RED then you have services which for some particular reason are stopped. Try restarting the services. It is very abnormal to uninstall and reinstall the PBX frequently. I suspect that there is a serious problem with your machine or with your operating system. If you plan to uninstall again, make sure that the registry is cleaned, postgres User removed, services are deleted. (These are all things that are done automatically but please confirm their removal manually). If you still do not work, send me the logs and I will take a look at them.
