Hi Justin,

First thing you should do is to update your R to 2.7.0 as your version is
about a year out-dated. Then see if you can load the GEOquery package.
Generally, you want to have the latest version of R and the packages so
people who maintain the software can be more help. Usually they don't/can't
help with outdated software.

Cheers,
