Unable to Create New condition in PAC Display windows manager

I am using PAC Display Basic 10.1a version.

Recently I migrate PAC Display Backup from 9.6 to 10.1a version.

Now, I am not able to Create new condition in PAC Display windows manager.PAC Display configurator is crashed after completion of tag selection option from a trigger option.

Thanks & Regards,

I have observed the below things:

When I am assigning small name Trigger variable(Delay_500) at that time it is working properly.

but while i am going to assigne bigger name Trigger variable (n_K1_Water_Rinse_Batch_Finish_Window_Popup) at that time PAC Display configurator will be crashed automatically without saving the data.

Thanks & Regards,
Aanand
