Hi, Mark.

The "Pro" version of PingPlotter is still not a real product, but the existing product has the start of some of the capabilities built into it. The problem you're having here is that PingPlotter thinks you're trying to specify multiple targets on the command line - and this is something the current versions don't support (although it parses them, it doesn't know what to do with them).

This is likely because of the syntax of the command line that you're using.

It sounds like what you're doing is loading an existing file and then continuing from that. To do this, use a command line like this...

"c:\path-to-pingplotter\pingplotter.exe" "path to save file\savefilename.pp2" /trace

This will load the file, and then start tracing. The quotes are quite necessary here.

If you use the syntax /trace:address, then PingPlotter thinks you're trying to specify a target rather than a file name.

If you have problems getting this syntax to work, post back here what your command line is and we'll help you craft a properly working shortcut.
