Pro not working

hi, pro installed, configured and started. does not work, not even in the slightest. I cleared the cache and tried another browser. I tried various other tools (free versions) eg. seed, all work right away. ideas?
I also uninstalled and reinstalled. I now had to block my page in a different way, but I imagined it differently!
