I'm a convinced user for over a year now, but this time I'm unable to solve the problem on my own

A few weeks ago I got a new laptop and set up the connection with a USB to serial converter. This worked fine after I realised I needed a software for the converter.
Today I wanted to change my map but I'm unable to connect again ...
When I have ignition switched on and I start the Megajolt soft I get the following Windows message :
Runtime error
I run the original soft that came with the Megajolt unit V4.0.1 and did not change anything from last time.
When I try to persuade the program to write a ignition configuration I get this message :
MGJL controller version 16.32.32 is not supported by this configurator
Anybody has a clue what I should do ?
Thanks
