Log messages for RISEEditor.exe

This is one of those ClickOnce apps.
The program can be downloaded from
http://www.risetobloome.com/clickonce/riseeditor/riseeditor.htm , the
RISEEditor.application file can then be started with wine start
RISEEditor.application provided dotnet40 is installed.
After installation, the actual executable is placed in some directory under
"C:/Users/$user/Local Settings/Application Data" and can be started directly
from there.

Starting up the actual application takes a very long time; it hits some sort of
timeout I guess. I've attached the log.
It hangs right after printing line 38,
