Hey Guys,
after spending a lot of time to fix my problem i´ll write to you. I hope that someone can help me...

A week ago i tested TunerPro to do some changes on a bin file.
I can save the file, correct the checksum with me7sum and me7check says everything is ok.

So i have read a lot about mapping and will now start an own tune for my project.

I load a bin file with matching xdf to Tunerpro and do some changes.
After that i´llgo to: Save bin as, name it and press ok.
Now i become an errormessage:
"Error - One or more checksums could not be updated. Check checksum addressing, etc, for validality"

So, i´m wondering what i´ve done wrong. At first test a week ago there was no problem to save the file.
I read something and re-installed tunerpro after uninstalling and delete the TunerProFiles directory at documents.
I tried another computer, same issue.
I tried other bin files and other xdf files.
Even if i´ve nothing changed on the bin i´m not able to save the bin.
->open stock bin with matching xdf, change nothing, got to Save Bin As, same error...

I don´t know what i should do now...

Please help me

Much thanks,
Flo

Oh thanks for that!!!

Now i can save the bin file without an error message...

My new issue: me7sum can´t correct the checksum on my bin file
I tried some other bins... Same issue again...

I don´t know what´s happened, a week ago everthing worked fine and now... problems over problems.

Thanks for your reply and your help... perhaps you´ve another idea?!
