Hi @suhaib,

There are two issues I noticed:

  1. The date time format in your file is wrongly stated and it will have to changed

  2. The Invalid format of the .p4d file.
    The .p4d format conversion is automatic when upgrading a project, meaning when jumping from one version to a more recent one. However if the gap between versions is too big, the conversion might fail and this is why this problem is occurring. Which PIX4Dmapper version are you using?
    What is the email of the account you are using?
