When I connect my TI84 pus silver edition to the computer, the DeviceExplorer in Ti Connect detects it. And when i click a program and drag it onto my desktop or anywhere else, I get the following error : The device does not recognize the command. 
The same thing happens when i try to drag a program from my computer to the calculator. Can someone please help me fix this problem?
Oh and I dont know if this may also be an issue, but when i check for updates, Ti connect isnt able to detect my calculator even tho Device Explorer can . :( :( :(
