Ok, I am getting close to working my nerve up to trying out the new WinMx.
Can I install this new version over the old version?
Or...
Should I unstall and delete the old one before I install the new one?
Just shut the current one down, and run the installer for the new one. It will install right over the old and you shouldn't even have to reconfigure it.
It is best to install the newer version over the old, because all of your settings will be intact. That will save alot of time and hassle.
The new version is almost the same, except for a few extra features in chat.
