Teamspeak problem

hi, i used to have ts and never used vent. But a few months ago i started using vent aswell and someone advised me to download ventmix (so few vent versions+ts), since the day i downloaded it and installed it everytime i start up Ts it keeps showing the ip + name that were filled in before i downloaded ventmix. :S
So whatever i fill in, everytime i start it up it constantly shows an ip that i only needed ages ago, and i just want it to remember the the ip i used last. I've tried deleting both and installing only ts and later on only ventmix but it still didnt work. Anyone got idea's how i can fix this prob. so that my ts will remember that last used IP/name and stuff everytime instead of one i just 8 months ago :) thanx
