im_msvistalog Assertion Failed

Hi,

I'm trying to read from a .evtx file directly using the File directive in im_msvistalog. I keep getting an error: Assertion failed at line 1945 in im_msvistalog.c/im_msvistalog_start(): "((nx_im_msvistalog_subscr_t **)(imconf->q_subs->nelts-1->query = imconf->_query""

I'm running Windows 10 with nxlog-4.0.3550. I've tested with different files with the same error.
