Load fails; Warning raw channel

First time using UE4 on new O.S. (w7), and though it worked flawless last month, now I get ;
[1129/104008:WARNING:raw_channel_win.cc(532)] WriteFile: The pipe is being closed. (0xE8)
[1129/104008:WARNING:channel.cc(359)] RawChannel write error
[1129/104620:WARNING:raw_channel_win.cc(532)] WriteFile: The pipe is being closed. (0xE8)
[1129/104620:WARNING:channel.cc(359)] RawChannel write error

another log shows about 100 failed to read errors, that in itself is a question; Which log file am I supposed to be looking at? There are 4 ; 1kb, 20kb, 28kb, and 144kb.

first says cdf3, others just say EpicGames Launcher

I tried to see if anyone had this issue, but the code itself was needle in a haystack.
