Thought I should post this, in case someone else is having the same kind of problem. I don't think this is a very common problem but you never know, maybe someone else out there needs to know that this can happen.
First of all, I can watch the cams again and I am SO HAPPY!
My problems started on the 13th, could see the commercials but no streaming. I spent the next days slowly going mad and checking everything that could possibly be checked on my computer and trying all solutions that are posted here and on the internet. Nothing worked. All I got was connecting... ready... black screen. Again and again. Also couldn't access onenetplace.net which I believe are handling the streaming here?
Finally I contacted my ISP. First they told me it was a problem on their side that should be fixed by Monday. It wasn't. Today I talked to them again and found out that my ISP Telia has a conflict with a company called Cogent that handles internet traffic between my ISP and the US and they have cut my ISP off! How crazy is that?!
I am sure this is why I havent been able to watch the cams as I have switched to a 3G wireless modem from another provider and it works just fine. Very happy here.
Maybe this information can be useful to someone, but I hope it is a very rare problem because trying to figure out what is wrong is very likely to drive a person insane, LOL. I think I'm OK now, though.
