Hi,

You should check .cif file permission of the guatemala file in:
/public_html/sites/default/modules/ubercart/uc_store/countries
permissions should be 644
(f.e. with cpanel use file manager, with ftp tool check properties)

Then it's may look stupid ... be sure your user have ubercart permission to admin store (admin/user/permissions):
uc_store module > administer store

If your database isPostgreSQL you should use this modifyed and tested cif (country column names added) to avoid the following bug (fixed in uc 2.3):

Anyway you should plan to upgrade drupal and uc (at least for security reasons : http://drupal.org/node/880476) following http://drupal.org/upgrade
