Please, Please, Please, help

After I connected my laptop to a LG Master-K120s PLC through KGLWin3.6 I hit the Connect+Download+Start+Monitor icon on the toolbar and my old program vanished. There is any way to get it back?

you mean that you downloaded an empty project to your plc and would like to come back to the previous program that you never saved ?

i don't see any option with plc brand i know....you're locked outside! I believe you have to look for a back up file or contact the manufacturer of that equipement to get the original program....

Thanks for your reply Jeff
Yes thats exactly what I did, stupid enough?
So I am out of luck, thanks anyway

yeah **** happends....

i did it manny years ago... i was using a co-worker laptop configured in french instead of english and i mismatched upload/downlod button and did same as you....My luck was that the customer had a backup copy but they made changes since and i add to re-do everything myself.....

Never again! i remeber it even if it is 9-10 years ago...

A good option to avoid that is to lock the plc with a password if availaible...sometimes you can allow upload and block download of changes...
