OK, after some testing I think I found the problem.
Normally, synctex files are written with the unix line ending
convention, i.e., every line is terminated by a single linefeed
character (\n, 0x0a). On Windows, lines are by default terminated by
carriage-return + linefeed (\r\n, 0x0d 0x0a). As synctex doesn't expect
this, Tw gets filenames that have a \r appended, which obviously are not
found on the system.

So, the solution is to take care of preserving the line ending
convention when editing the file. This can even be done in Tw itself. In
the editor window's status bar, the leftmost field (not counting the
general message area) must read 'LF', not 'CRLF'. To change it, simply
right-click on it. Then save the .synctex file. It might also be a good
idea to close Tw before opening the .pdf, to make absolutely sure
nothing is lurking in some internal buffer.

As Paul mentioned, the .tex file was not accessible. The other files
were, however, and since the .tex should be circumvented that was OK.
