can't get nothing to work, at a loss here. Errors everywhere, versions not correct

Question

Hello developers, 
 I've got an nrf51822 EVA kit with on it the QFAACA chip. KEIL v5.0.5, J-link V4.78, nRFGo Studio V1.16 and nrfGo SDK (zip) V4.4.2. The Softdevice on the Dongel and the Board are both the V5.2.1. 
 To measure the current I've cut the short and soldered a 10-OHM resistor on place. 
 Problem: 
Something is wrong, I can't even get example file Blinky working. Compiling works great as always, Loading is the trouble. I get two errors in a row:
 
 and: 
 
 with KEIL error code: 
 
 I've been breaking my head on this board for the past two weeks and I only figured out how to set the GPIO-pins. 
 Thanks in advance.

Could it be that you have a softdevice programmed on your chip? If so, you need to do an erase all to be able to write blinky, or you have to use the s110 target in Keil's drop-down. 
 The last error seems a little odd, though. Can you please make sure that the file it's complaining about is actually there? It may also be useful to try to do a reinstall of the nRF51 SDK.
