Ekreks

Hello. I am on release 4.05 and have been having issues logging in with Chrome and IE so decided to upgrade. When I try manually I get an error invalid or incompatible upgrade file. I have the isy 994i more recent release replaced my order unit some time this year. I just realized in Help->about the product is showing unknown which I suspect is the issue. What guidance steps can you supply to resolve this? thanks David
