how can I fix this problem? please help
This specific error happens when a singleton (model or helper) is attempted to be invoked but cannot be mapped. Based on the path which I'm seeing in the stack trace, it looks as though you have compilation enabled. You should disable compilation while attempting to install this module, which can be done in the admin GUI at System > Compilation.
