Timeline reports error - cant' see other tweets


Hello there,
I found this Threeter the best lightweight twitter client out there. May not be the most complete (following hyperlinks would be great), but I like it. I would even donate the project, but I don't know if it's alive or not...
Well, the problem is that when getting updates from the ones I follow, I can't get them. The strange thing is that the balloon that pops in the taskbar shows fine, but then the timeline window shows this error (attached picture). Moreover, by choosing individual names in the timeline, this works.
If you can work it out, I would donate very happy.
