DW Spectrum updates issues

Hello, 

there are some issues with DW spectrum updates:

update from 5.1.3 to 6.0 broke support with some Geovision cameras; the DW support spends few days online but unable to solve; I had to reinstall 5.1 version

update from 6.0 to 6.2 broke support with Hikvision analog DVR; all analog cameras appears offline; downgrade to 6.0 and everything works well;

any solutions to those issues?

thank you.
