STM32 Nucleo F334R8 shows FAIL.txt file and am unable to debug board in IDE

Associate II

I am using a STM32 Nucleo F334R8 development board and upon plugging the board in to my PC, windows file explorer shows a FAIL.txt file with the following text: "The interface firmware FAILED to reset/halt the target MCU". This file first appeared after i successfully uploaded a .bin file from MBED website example program. When trying another example program the FAIL file showed up and now when I try upload another .bin file, I am told I have insufficient storage. It shows I only have 8 Kb of memory free.

This is the first time I have used MBED, so I tried using TrueStudio to upload an old project and the debugging failed. If anyone knows how I can solve this issue that would be appreciated. I have updated the drivers on my PC and upgraded to the latest STM link.
