HSG comes without support and it was discontinued (it's not developed anymore since 2002, 19 years ago), so, please take it 'as is'. Anyway, if you want, please give more details (because "the URL dialog gets some faults" is not clear enough to know which 'fault' or issue are you getting). Leave more details, like your operating system, and please describe better your problem (but don't expect any new fixes to HSG, since development ended long time ago).
