Under tools, options, profile, there is a reset button. Have his messed up profile set current and reset it.
This will then set it back to the installed default profile.
I'm not sure how you have set up your profiles, but unless you hard coded each individual path,
your should be able to mimic his with yours and the appropriate changes.
If all else fails and you are brave enough. Start, Run, regedit and enter the registry.
What profile names are you using? Is it just the un-named or set by user, client, company?
How do you incorporate your specific company search paths into this profile for your individual users?
If you open up your *.arg file or drop into your registry, your paths should be set by something similar
"TemplatePath"="%LocalRootFolder%\\Template"
"PlotLogPath"="%LocalRootFolder%\\"
The %variable name% is the part that changes for the different users. As long as your profile is
setup this way, it should work for him as well.
