Color profile problem after updating photoshop

[fffragosi]

I made a psd file on my previous photoshop version and exported it to png. Today I opened that same file after updating photoshop to the newest version and the colors are completely different. I've tried changing the color profiles and nothing gets the colors back to the original ones. I've tried exporting it and it's still very different...

ORIGINAL COLORS

COLORS NOW

I don't really know what I could be doing wrong - I've tried pretty much everything, I think... On the preview of the .psd file I still see the original colors but as soon as I open the file on photoshop, they change...

I used Adobe RGB 1998 on the original psd file.

Thanks!
