LimeWire makes "new volume"

Please help!
I have my shared-folder on an external hard disk named for exampe “abc“.
Now LW calls it "abc 1" or "abc 2" and so on. Going from LimeWire and clicking on search shared-Folder I can reach it, but on the volume I can´t find it anywhere. What´s going on there?

…and when I try to select a new shared-folder and select it from the volume, LW counts a number further. When it was before “\abc 2\shared“, it becomes "\abc 3\shared"
