May I first ask that you write in normal font rather than bold and italics - it's rather hard on the eyes for some of us!
With regards to replays in the blog, I have millions saved in my blog. Ok, not millions, but lots and lots. I think I may know where you went wrong.
I suspect you saved your replay to the Replays section on your profile, then used the Share link from there, copied it and saved it onto your blog. Then you deleted the replay from the replay section.
The problem with that is the link that is now in your blog is to the replay which was in your replay section (now deleted) and not the one that would have been held on the WGT servers had it been done properly.
As Bob said, when you want to save a replay during a game, check the Save Replay box in the bottom left of your screen. Then on the next screen click Share (not Save). On the next screen click Copy. Then go to you profile and into your blog. Now type something in there, then click the Link button on the toolbar and paste the link into the URL. Then when you want to watch the replay in future all you have to do is click in the link in the blog.
Hope this helps. If not, let me know and I'll make a video of the procedure.
