MY FREAKING HOLOSUN EPS CARRY RETICLE STUCK - HELP!

Okay guys, You won't believe this having a major issue with this Holoson EPS Carry. The reticle is completely stuck. I've tried everything - taking it apart, cleaning it, adjusting the settings, but nothing seems to work. It's like the whole thing is glued together. Has anyone else ever experienced this issue? Any tips on how to get it moving again
