Over the past week I have experienced many failed attempts at downloading Data and System Log information from my single screen AFS 4500. I bought 2 each 2 GB SD cards (1 each for System Log and 1 each for Data Log), formatted each using FAT32. Did the download (message that download complete). Inserted the SD card individually into my Windows Vista laptop, and when I open the SD cards I get the following:

For the Data Log (ALD) I get a message (paraphrasing) Windows cannot open this file. Windows needs to know what program you want to use to open it. Options - go online to determine a program or select from a list.

For the System Log (ALS) it opens a spreadsheet in Windows Excel where columns A - D and lines 1 - 32 are populated with the following: INFO:Valid NMA GPS Time Detected.

Anybody out there that can help me "break the code" on this?
