I was on WP ver 3.0.4 and this plugin (ver 0.0.50) failed. It installed fine (using Add New Plugin option) but as soon as I clicked on Activate, it crashed the whole plugin section. I had to delete the wpdojoloader folder from /plugins in order to get the plugins section on my admin cp to come up.
I upgraded to wp ver 3.1 and it's still failing to activate. I even tried your previous version 0.0.42 but no luck. I'll have to give up and move on in a short while. Please help.
