after downloading a mp3 file they used to be saved to the one folder. Now after updating to Limewire 4.14.10 my files paths says they are going to the same place but they are not and when a error message asks if i want to change path limewire does not open. HELP!

Try deleting LW's preferences folder when LW's properly closed. See point 3 here & also point 2 if you've used older versions of LW in the past (there could be a folder in either location).
Fixes for LimeWire
This will change all of your settings within options, you'll have to go back through afterwards & reset things. If you're not sure of your settings, go through LW's tools > options & write them all down, so that you can reset things later.
In case you're using Vista: LimeWire Pref Folder in Vista

Once you've deleted that folder & things are set back to default, try going in & changing the location for saving
