I recommend using some terminal emulator which supports ymodem protocol (SecureCRT, minicom, ...) for flashing the WifiMCU, not the WiFiMCU Studio.
If you cannot start the WiFiMCU in bootloader mode, the only way to reprogram it is with ST-LINK programmer. It is quite easy, I can give you detailed instructions if needed.
If you have one of STM-discovery or Nucleo boards you can use it, otherwise you can by ST-LINK for ~3.3 US$ (ebay)
