When you plug your SD card into the computer what do you see?
There should be a folder called "Record" and in the file there should be at least to one folder called R00001 (or higher number) and a file called the same R00001.dat. Inside the R00001 folder there will be 8 more files. If you do not have these then you may not have recorded anything. One thing to remember is anytime after you "Start Recording" you must "Stop Recording" otherwise the files will not have an end of file locator and the recordings will not show or work.
If you have these then go to --->
http://humviewer.cm-johansen.dk/ <--- you can download this software, follow the directions and you should be able to view your recordings.
I have not played with the other ones for a long time so I cannot speak for them. If you key "Forum" and scroll down the page you will see "Software and Software Development" there are more programs available.
