Sorry about the badly formatted message.
Regarding the second error again, here's some code that will help you debug that one.
According to the documentation, OleCreateFontIndirect returns E_INVALIDARG, E_OUTOFMEMORY, E_UNEXPECTED, E_NOINTERFACE and E_POINTER errors.
Eucom has routines to check for errors, they're just not used there, until now :)
On eucom.ew, quick_activate function add below the line:

    ok = c_func( OleCreateFontIndirect, { pfont, riid, ppvIFont } ) 

This code:

    if is_error(ok) then 
        com_err_out(1)  -- Print the error on console 
        com_error(ok)   -- Display the error on console 
        while get_key() = -1 do -- Wait for key press 
        end while 
        ?1/0 -- Crash 
    end if
