had a problem with socks vip72

[notspec]

im a noob, i bought vip72 yesterday trial 10days, installed proxifier, everything was good, ip not blacklisted, changed my ip many times..
today turned on pc used proxifier, everything good for some hours, after i get a pop up window from proxifier saying to change settings so i click ok, proxifier couldnt connect to socks. after 3h of trying to fix i was able to upload first profile on proxifier and socks worked again.
error was <Local DNS service is available. Name Resolution through proxy is disabled>
now i was able to fix the problem, but how can i avoid this happening again. what does that error mean?
sorry for bad english
