File Permission Error; NI-488: DMA Hardware Error Detected

I'm having an issue running a labview based program. When it tries to collect a data point and write to the file I get the error:

File Permission Error; NI-488: DMA Hardware Error Detected

I'm using Labview 8.2 on a MacMini running OSX 10.5.8. I've set the program specific permissions to allow reading and writing, yet I still get this error.

Any suggestion? Thanks in advance!
