Thanks for the help. I was able to delete the admin_pm.
But the install_pm and webassist folder found inside of it can not be removed. I still get an error similar to the one I sent in my previous email. I also went inside these folders and deleted what I could.
Some folders, could not be deleted.
Attached is a file/directory tree showing my site files and I have powerMessenger expanded so you can see what files could not be deleted.
1. What next? Any advice or should I contact my webhost?
2. Can I install powerMessenger (the correct way) now? Or do I need to wait until I figure out how to remove install_pm directory.
