[TxMt] "Edit in TextMate" not working

I have installed the "Edit in Textmate" bundle, with apparent success, except that when I invoke the function, either through the hotkey combination or by selecting the item from the edit menu in Safari, nothing happens. I simply get the OS X warning sound. Looking in the console I see the following:

2007-07-07 01:17:38.606 TextMate[9345] Can't open input server /Users/chris/Library/InputManagers/Edit in TextMate

Not sure what this is all about, since this link does actually exist, and links to the folder in /Applications/TextMate.app/Contents/Resources. Any idea how to get this working?

Thanks in advance.
