[2004] Microstation Key-In Issues

Hi,

I'm having difficulty using the Key-In function to open and draw from text files. I set a function key (ctrl+F9) to "@C:\CAD\KeyIn.txt" and it was working properly a few days ago. I decided to change the directory to my working folder (still on the C: drive) and moved the text file accordingly. Now, whenever I use the Key-In function I get "Unknown key-in or command." I've even tried reverting back to what worked previously but no luck. Has anyone encountered or heard of this issue before? I am currently using 2004 V8. I remember running into this issue when I first started using Key-In commands but unfortunately I do not know how it was (seemingly magically) resolved.

Thanks
