Fails to import PRN or CVS

Hello:
Just purchased the software . One main selling point was file importing. Unfortunately the program fails to import both CSV and PRN files. I get the error message - "The file to be inserted will not fit if it is inserted at cell A1". I highlighted all cells and the importing operation failed with the same error message. I uploaded the two files I tried to import at the links listed below.

CSV file

PRN file

Screenshot of message attached. Thanks.
