xlsread problem

I have these strange problems using xlsread. Sometime it reads in the data fine and then other times I receive this error: "??? Error using ==> xlsread at 234 XLSREAD unable to read sheet "Sheet4". File does not contain recognized Excel data. Try saving as Excel 98."

I erased the data in the offending spreadsheet and pasted in data that xlsread was able to effectively read-in and received the error again. So it seems the error is not in the data itself but inherent to the spreadhseet. It seems to me very random when this problem occurs. Thanks for any suggestions.

I need help with this exact same problem too! 6 years on!

I've attached my xls. I can't understand why I can read some sheets but not others.
