I'm having the same problem. I can't run 2.10 on my pc.
Is there any way this can be fixed to run on 2.5?
If not, I guess I can't finish this quest.

Here are screenshots of before and after I paid the fee. I've tried walking everywhere and pushing every block, no luck.
...
Whack me on the head, please.
... Thank you.
I finally found the problem. Turns out that when I was playtesting, I found out that my animation combo had the wrong block sprite. Sooo what did I do to fix it? Put a different combo with the right sprite on it!
Whack me again, please.
... Thank you. (Ouch! Okay, I'll stop now. I'm just feeling like a complete idiot right now...)
I'm so, so sorry that me and my idiocy has greatly inconvenienced you and anyone else trying to get through this.
I've fixed the problem by pasting the correct sprite over the animation sprites and placed the animation combo in the secret combos. To make it up to you guys, I'm posting an update tonight, even though it's late and I have school tomorrow.
Why doesn´t the wand work on these bushes ?

Just the wand, by itself, won't work. Do you have the Magic Book to cast wand fire?
I'm still stuck in Level 5. I got the item from the question mark room, and the only two passages I've found go to an isle with a heart piece, and the other goes to the path leading to the boss room. Do I need super bombs to access another dungeon, as the guy said, or is the way in the dungeon?
This is where I have been:

Go to room 07 (the upper-right corner of the map) and beat the wizzrobes; they'll drop the boss key. After getting the boss key, go south. The boss isn't in that room, but a passageway leading to the room next to the boss. (Don't be fooled by the boss-lock door. If you don't hear the boss roar, it's not the boss.)
Oh, and BTW, you missed the compass in the room immediately to the east of the entrance; beat the enemies there to get it. 
Also, FYI, there is a man in the eye and something great in the mouth of the snake on the map (if you haven't found them already).
