To add an attachment it needs a name that has not been used before. Because Mach3Mill.xml will have been used you will need to copy the xml to your desktop and rename it then attach, suggest you call it ranchak.xml
Dont know why you get that error, must be Yahoo will not send xml files thinking they are a virus.
Best bet is to PM Terry and see if it looks like the problem he suffered from and if he found a cure. Last I knew the only way he could get rid of the problem was delete the Mach3 folder and reinstall Mach anew.
