Macro works on One computer, but not on another

[Space_Antelope]

Hello, new to this forum and VBA for the most part. I need some help. My code bugs out at a certain spot every time on my work computer, but when using the same files on a different computer, it runs without a hitch. I've done some googling on what might be causing this, and I've checked the references and they all match on both computers. Any thoughts? Code is below.

lastR = ActiveSheet.Cells.Find("*", searchorder:=xlByRows, _
LookIn:=xlValues, searchdirection:=xlPrevious).Row
lastC = ActiveSheet.Cells.Find("*", searchorder:=xlByColumns, _
LookIn:=xlValues, searchdirection:=xlPrevious).Column

Any help is appreciated. Thanks!

To add some additional info, I have recently re-installed Windows 7 on my work PC. Also using Excel 2003.
