Since none of us (as near as I know) can read minds,
it’d be a BIG help if you told us more about your system.
Is the emoncms you installed on a Windows machine? A Linux box? Which version of Windows / Linux is it running on? Is it the pre-built version? If so, what is the version number? Or did you build it yourself? What have you tried that’s not working? What else have you tried? Did you change anything? If so, what was it?
Do you see where I’m going with this? The more info you can give us, the more likely someone will be able to help you. Please be as descriptive as possible.
