I have been trying to use PROS for my own VEX uses, but cannot upload code to the Cortex. My computer running Windows 8.1 recognizes the Cortex, and programs such as ROBOTC can successfully upload to it. However, PROS cannot. The firmware has been updated, and I have tried running PROS in compatibility mode as well as reinstalling it several times. Also, running as administrator does not help.
The Cortex itself is not the issue, as code can be uploaded to it (tested with a friend's computer running PROS).
When run from the command line, the issue looks like this:
UniFlash v0.7 by Stephen Carlson
Error: No matching ports found for this board (VexFlash); currently connected:
* COM8 (Hardware Serial)
Please advise as to how I can resolve the issue, and if any more information is needed.
