Hi, I get this message too. I have tried adjusting the text / number format. I have tried copying and manually inputting the data. I have tried using just a few data values, and all of them (approx. 200) but to no avail. When I click run regression the computer takes ages to determine the run time message, and when I click end, it has changed the number of observations from its original value to 59997 after having put 0's in all the rows beyond the data. I can't understand why this might be happening. Please help. Thanks, Jack
