I have had my MPVI for some time now and used it many times, the last time i used it was a week or so ago. I went to use it today and I got the invalid app message. I really need to get this up and running for a dyno session tomorrow.
any help would be great!
I have the same problem, they just told:
["Unfortunately this is the only option I can offer in this case.
