What does it mean when importing a .inp as a model results in the error message

NoKeywordsDefinedError:  This occurred while scanning input file for fixed format and parameterized data.

No part appears and no other output is produced. Also the input file cannot be run: 

PS C:\\Users\\pkonl\\Downloads> abaqus job=part1-frequency1
Abaqus Error: There are no keywords defined in the input file.
Abaqus/Analysis exited with error(s).
PS C:\\Users\\pkonl\\Downloads>

Now, I can clearly see that the input file defines a lot of sections (keywords are there!). 

Any ideas?
