LBT 1.5.0 Access Denied


I couldn’t run annual daylight simulation, error: fail to create sky. And I found earlier posts where Chris advised to update by versioner.
However, after updating by versioner, the whole LBT is gone (LB, HB, HB-R, HB-E). When I open grasshopper, I have this error msg:

My IT support says they don’t know how to solve this problem.

Just to give an update: as I haven’t heard of any reply, I just re-installed the pollination, so far it works fine.
