I've had that same problem but I went away for a holiday so didn't have time to fix it.
Possibly found a simple fix, just download the newest version and try. The script works slower now, giving more time for other things.
Downside to the fix is that the links might take a long time to linkify if you have many friends online but I can't test it at the moment because there's only 3 friends online at this hour. When there's more, I can test the fix better and perhaps improve it a bit.
If it works now, let me know.
