yeah tried reinstall no good.had the tech guy on the phone going thru the setup and he told me it was some kind of update problem and i`m stuck with it till they get it figured out, i`m not holding my breath .been having alot of problems with nightowl products lately.my cameras down here in mexico started dropping out this summer will i was back in the states so i brought down a new dvr and cameras .i couldn`t get it to go online and after multiple phone calls and higher up tech guys was told the unit was no good and send it back for a replacement.so now i have to wait to get back north to send it back.meanwhile i had to go back to my old unit which works fine now with some camera and wire swaps.long story short i`m done with nightowl,you get what you pay for i guess.just looking for another programme to view and record.
