Hello, after updating to 7.5.3 from the previous version (which I believe was 7.5.2, I don't remember for sure but I update every time there is the option to do so) tor initially seemed to be working fine. However today I updated my Windows 8.1 install and after the update for whatever reason tor would not load. It kept giving me an error saying

"Tor exited unexpectedly. You must restart tor to fix this problem etc"

but no matter how many times I restarted tor this did not fix the problem. I then reinstalled tor to a different directory and then tried to start it up and surprisingly it worked just fine, but after setting up the bridge and the socks5 proxy I use again it told me that the settings could not be saved because it either could not connect to the host provided or could not parse the host name provided. I used the same proxy for firefox outside of tor and it was working fine with foxyproxy so it has to be with your parsing method.

I don't know if something changed in the windows update to affect how proxy host names are parsed or if there was a change in 7.5.3 but if I type in the IP address instead of the domain name it works fine. I would rather not do this though because the host name automatically switches between about 200 different IPs for the fastest connection on the network so this way I am stuck to using 1 IP address.

I also read online when looking for help initially that someone else had run into this problem and was able to fix it by running tor.exe separately and specific from the firefox.exe executable in the tor browser folder. His issue must have been do to something else because I tried this and it did not fix anything.

Can you please look into this for me? Or at least tell me how I might fix it so that I can provide a host name instead of IP address for my SOCKS5 proxy? the current host name looks like:

and before i just typed it in just like that, no protocol description or anything at the beginning and it worked just fine up till now.
