MSP432 Red Launchpad Error Loading Code

Hi,

I am using the red MSP432 launchpad, and I have had a few stop working, so I am trying to figure out why. Whenever I try to upload code to them (any code, it doesn't matter), I get the following error:

CORTEX_M4_0: * WARNING *: The connected device is not MSP432P401R
CORTEX_M4_0: GEL Output: Memory Map Initialization Complete
CORTEX_M4_0: GEL Output: Halting Watchdog Timer
CORTEX_M4_0: WARNING   : On MSP432P401R hitting a breakpoint cannot be detected by the debugger when the device is in low power mode.
                         Click the pause button during debug to check if the device is held at the breakpoint.
CORTEX_M4_0: Flash Programmer: Reading HW revision failed.
CORTEX_M4_0: Your XMS432P401R material is no longer supported. We recommend you moving to production-quality MSP432P401R/M silicon by ordering samples at www.ti.com/product/MSP432P401R.
CORTEX_M4_0: File Loader: Memory write failed: Unknown error
CORTEX_M4_0: GEL: File: C:\Users\Matt\Documents\VT\Research\Heat Flux\MSP432 Code\UART Test\Debug\UART Test.out: Load failed.

I am using CCS v6.2.0.00050 with msp432ware__3.50.00.02, MSP432 Device Support Files v6.3.1.1,  and TI Emulators v6.0.407.6 . Does anyone know why I might be getting this error?

Thanks,

Matt
