File Manipulation Lab

I’m working on the file manipulation lab (RE Course Challenge #5.exe) and have run into a problem. I created the file the program attempts to open, but I keep getting a file not found error. I have confirmed the path and filename are correct. I can use the path from the program to see the file. I’ve also checked that all user’s have permission to read the file and even tried reloading OllyDbg to ensure there isn’t any caching problems. Does anyone have any ideas?
