[split] cannot create gui

Hiya, Apologies if this is posted in the incorrect forum but I have just downloaded and installed Krypton 17.1. When I hit run, the screen goes black and i get an erro message – “cannot create gui”.
I have tried other aspects such as deleting the addons27 which is mentioned in other answers but that has no effect.
I am running Windows 10, Lenovo laptop. The log files are below:-
Thread 15984 (process 11520)
# 0 RtlWaitOnAddress
# 1 RtlEnterCriticalSection
# 2 RtlEnterCriticalSection
# 3
# 4
# 5
# 6
# 7 o__CIpow
# 8 BaseThreadInitThunk
# 9 RtlSubscribeWnfStateChangeNotification
#10 RtlSubscribeWnfStateChangeNotification

I know it is something I probably need to do but any clues
