So not cool, be careful installing

Although I noticed the note that this version is not compatible with my WP version, I tried to install this plugin, since mostly, it still works. Except this plugin. When trying to activate the plugin, my database crashed and my website went offline. I managed to disable the plugin through mysqladmin, and got my website online. So bear this in your mind when you also have the most current version of WP and want to use this out-dated plugin.
A word to the developer: Is it possible that you modify this plugin to being compatible with WP again? Since it was almost 6 months ago you updatet this plugin? Thanx in advance ??
