I have tried every thing I know how do do in order to download the Portable TB application. All without success. I got a page not found at SourceForge. Several times I got an indication that the page was loading; but when I got the "Done" message; there was no download page nor had any download appeared to have tried to begin.
Well here I am four and a half hours later and I am getting a download from sourceforge. :-}
Nothing changed on this end, so I suspect that something changed either at sourceforge or on the Portable Apps Site page.
