Everytime I take out a cd from my disc drive I get an error from litestep.exe saying there is no disc in drive d:. I have the option to cancel, retry, and continue but Even if I click one it won't continue until I insert a disc. How do I fix this problem? It's annoying. Thanks.

What you want to do is remove all removable media from your popup.

And make sure that rainmeter isn't set up to monitor your cd drive.

remove media from my popup? how do i do that?

there's probably a line in your popup.rc that says something like "*Popup "D:" d:\" or something similar. just delete it.
