Can't install. Joomla ver 1.6.1, Table JX v1.5.8

I am trying to install using the Extension Manager in Joomla, but it begins to upload the file (table_jx_v1.5.8.zip) and it never finishes. No error message or blank screen... it just goes like it is a very long file to upload and never ends.

I already installed successfully other extensions. The server is CentOS w/C-Pannel.

I did uninstall form Extension Manager, Manage and found 'grid' installed, so some components got installed.

I also tried installing via "Install From Directory" but I get a different error:

Fatal error: Call to a member function enqueueMessage() on a non-object in /home/enkandas/public_html/selfcare/administrator/components/com_grid/install.grid.php on line 155

Please HELP!!!
