Did you follow all the recommendations by the plugin author, regarding installation?

I installed it, and I am having no problems so far.
Yes I did follow all the instructions. It was when I updated to the new version that problems started occuring. Plus my wp-contents zipfile is getting to be over 100MB, so maybe that is the problem? Still have it de-activated.
I have the same problem. I just installed it for the first time. Totally took everything down, I had to delete the plugin through FTP. I tried changing the folder back and forth from 777 and 755. No luck!
I did get an error statement one time about memory usage … My site is brand new and pretty empty though, so I’m not sure what the problem is.
I’d be very happy to try this plugin again if updates are made!
