Congrats. Rebooting likely won't help. Normally, I would call this a firewall problem, but...you seem to be getting to the folder, and the "cop" guy isn't coming on. Do these things:
First, put a folder just under AC and put a text file in it. Call it Test Firewall. Given it full permissions. Then see if you can browse to that folder, open the text file, tead whatever is inside it, change the text inside it, then close the folder. If you can do that, you have read/write permissions to a folder on the same drive as AC. So, now it is likely the port issue with 61067.
Turn off the firewall completely. Sounds like you have already done that. If it works, you need to make an exception for AC or Port 61067. If other computers can get to it, then it isn't likely that.
OK, and this is the important thing:
If you have, ESET, Trend Micro, Avast, MBAM, AVG etc., keep them. If you have either McAfee or Symantec, delete it completely off your computer. Don't just turn them off. Completely delete them. Symantec can be tricky. You will want to Google Symantec/Norton antivirus removal. Your best bet is a registry removal, but a good removal program will work as well. Don't just uninstall from Add/Remove programs.
If your Symantec is an antiviral suite, you can bet everything that it is the problem.
