If other phone software is installed on the machine, it could be causing the conflict.. Try uninstalling ALL PC Studio software and all other phones software on the machine, then download and install the most recent version of PC Studio, if that's the program you prefer.
Hope this helps.
I'm connecting my cell phone (Samsung Mythic) to my PC to add files and whatnot...I'm receiving an error message saying PC Studio can't connect to my phone because it's being used by another program. To my knowledge, I don't have anything running that would be using the phone. I need a way to figure out what program/process is using my device so I can shut it down and access the phone. Thanks in advance.
