Thanks. For Windows users (sorry, I only checked on Linux), a new version
of capabilities.R is now available adding the mode="wb" flag to
download.file() - the absence of the flag was corrupting the saving of the
auto.dta file, because it was not being saved as binary - it is now,
checked under R 2.2.0 and 2.2.1 patched under Windows XP.
