Yes. The clue is in the last line of your .bash_profile quoted above,
which loads your .bashrc, using the source command. It works from the
shell prompt too:

  $ source .bash_profile

Much less intuitively, the source command can be abbreviated to a single
full stop, so this does the same thing with less typing:

  $ . .bash_profile

Note that source simply runs the commands in the file; it doesn't
'unrun' any previous commands. That means adding or changing something
in .bash_profile then source-ing it usually does what you want, but
after deleting something generally won't (because the command will have
been run previously, and simply not running it won't reverse that!), so
in some cases logging out and back in again is still the simplest thing
to do.

Hope that helps on this small aside, and good luck with solving your
main problem.
