Erase failed on Cortex M4

Question

Today I have recieved the new nRF52 Development kit PCA10040. I did a update for the nRFgo Studio to version 1.21.2.3. 
 The softdevice s132_nrf52_2.0.0 will be flashed without errors. The template from SDK 11.0 will also be build without errors. But when I try to load the template on the chip, I will get this error: 
 Erase Failed!
Error: Flash Download failed - "Cortex-M4" 
 Do I have to change the Target start adress for the IROM? 
 My is now: 
 IROM1:0x1B00 and size is 0x65000 
 IRAM1:20001F00 and size is 0x6100 
 Or what else is the reason for "Erase failed!"? 
 UPDATE: 
 It wont hit the err code. In the picture below, the breakpoint will never hit. If I set the breakpoint on SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, NULL); then it will hit the breakpoint. But I can not check what happens in the SOFTDEVICE_HANDLER_INIT function. Because SOFTDEVICE_HANDLER_INIT is defined in softdevice_handler.h. In this file I cant set a breakpoint and check the err code.

If you are using the S132 v2.0 SoftDevice the ROM/RAM settings should be: 
 IROM1: Start: 0x1C000 Size: 0x64000 
 IRAM1: Start: 0x20002000 Size: 0xE000 
 The minimum required RAM is 0x13C8, but I have set it a bit higher. The actual requirement will depend upon the configuration chosen at sd_ble_enable() time. sd_ble_enable() will return * p_app_ram_base . indicating the minimum APP_RAM_BASE required by the SoftDevice for the configuration. Please refer the S13x_nRF5x_2.0.0 Migration Document, found here . 
 Update: 
 You need to check for new updates in the Packs Installer, see the screenshot below.
