MassHunter Quant Error During Method Edit

Question

I have started getting the following error in MH 10.1 (10.1.733.0) while trying to perform method edit actions like copying calibrations between compounds, appending methods, deleting compounds 
 Any Idea what could cause this? I've also built some methods from scratch and got the same error, eventually I get a full crash of quant.

Hello DataFool_312 , 
 In that particular screen shot it appears you do not have a data file or batch loaded. There may be some method editor functions that will not work as expected if you do not have a batch loaded and a data file selected. It is generally best to have a batch created and at least one data file before trying to edit a method. Let us know if you still experience these errors with a batch and data file loaded.
