New gaps in my laminate floor, help!

Bought this house a little over a year ago, everything looked great then. Over the course of the past year or so, the laminate flooring in my downstairs bedroom started getting some gaps. One of them, smack in the middle of the room, is pretty huge. I've posted 3 pictures here:

3rd image showing the end baseboard where I took 2 wire coat hangers, bent a little "c" at the end, and slipped them under the baseboard and around the plank and pulled both with all my might, the thing won't budge....:

So, how can I fix this? If I can't shift it back into place somehow, then is it ok to fill it with another piece of similar looking wood cut-to-size, or will this gap eventually close or something by some miracle?

By the way, there IS padding underneath the planks (i can see it), the gap doesn't show the padding because the padding shifted with the plank.

Thanks!!!

 

That looks like a glue together laminate. Your going to need to take the trim molding off and you need a laminate/ floating floor, "slap bar" and a hammer.

 

So if I remove the base molding section (i'll probably just cut the 8" section out and then glue it back in, it's under my desk so doesn't matter much)....the slap bar & hammer will push it back into place?

Is there anything I should do to prevent the gap from reforming in the future? Glue it first? Put some kind of spacer in it underneath the molding or something?

Thanks

 

Yes, glue it. Titebond II or equivilent

 

Thanks, will give it a shot!

 

Just an update. I cut the baseboard in that area, the reason why I had such a large gap was the laminate floor had actually slipped UNDERNEATH the sole plate on my bottom floor so it kept sliding furhter & further. I used a self-made pull bar (using a cat's claw and another piece of metal machine-screwed to it) and hammered the floor back into place, then I put a shimmy by the sole plate so that the floor will push against the shimmy instead of going underneath the sole plate. Problem solved!
