Hi,
Was it working before or did you just install it? If you just installed it,
it may require that you open a particular port in the firewall for it to run
for web-based communications. Check the program documentation for
particulars.
If it was working previously, did you install a third party firewall or
reset defaults on the Windows firewall?
