i get this message "file error: data may have been lost" when i open a excel workbook up

does any happen to know why?

nothing seems to be wrong with the file when i look at it

am I getting this error because i worked on the workbook on a mac? because i only seem to get this message when i open it on a PC

 

[bleeet]

I put in this VB code in it works but i don't know if this is causing the message


Private Sub Worksheet_Calculate()
Dim i As Long
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
Application.EnableEvents = False
Me.Unprotect Password:=""
For i = 4 To 23
If Not IsError(Range("C" & i)) Then
Rows(i).Hidden = Range("C" & i).Value = ""
End If
Next i
Application.ScreenUpdating = True
Application.Calculation = xlCalculationAutomatic
Application.EnableEvents = True
Me.Protect Password:=""
End Sub

Very strange. I just started to see this exact error when I opened one of my VBA loaded workbooks.

Been using the workbook for years - I make adjustments to it now and then, but nothing out of the ordinary lately that I would think causes this error. I'm not working on a Mac, though.
