M-XXXX
looks like you are using the wrong plugin! look on the source setup window (the lowest window on your screenshot), you can find the name of the plugin at the top besides Data Provider. you are using the VT1103 plugin!
click on [Setup] in the graph window and then on the [Plugins] button. here you can uncheck VT1103.dll and check VT1165.dll instead!
Tnx, its working
