Okay, I got one for you guys

Hey hye, it's me again...
I've struck another barrier in my game development, see, every time my main
char. gets to a certain point in the game, his ablility to use his skills stops, so, for example, when I
access my main char's Swd Tech, and browse the list of techneiques, he can use the first one, Charge, an HP restorative tech, however, his other three where faded black, and every time I tried to select it, it would react as though I diddnt' have enough MP, it would make the Cancel Sound Effect, and nothing would happen...
Now, here's the strangest part of it all...
Sometimes, when I start a new file, to test it, and play through, it DOESENT happen, and sometimes, it does...
What the hell is going on??
It happens in a tower dungeon i've created, when you travel from Fl 3-4,
and right before this menacing creature is summoned...
Anyway, if anyone has had similar problems, and found a way to repress the situation, I would be gratefull, thank you...

PS: I've only ever played RPG Maker 1 and 3, 2 was too complicated for me when I was 13, so this
is the only PC based RPG Maker i've ever used, but the resources I can download, and the new battle system ius enough to feel like i'm on crack!!
A-ahem!
So, please and thank you!

 Never happened to me before.

 What were his three skills? Any parallel events in that dungeon? What kind of monster are you trying to use them on? Did you check if the hero doesn't just have the "Silence" status?

No, he is definitly not silenced, I know this because it's early in the game, and no enemy so far has been able to inflict that ailment, his other three abilities are normal damaging abilities, Dual-Slash, Flame Pulse, and Ice Pulse, he's not trying to use it ON a monster, but he is disabled from using them BEFORE the boss fight, and no, no parralell events... Well, I don't know what a Paralell event is... Never had any run in with it yet, I guess, but i'm sure that's not it, see, it seems to happen whenever my Main Char travels from 2nd to the 3rd floor, he just can't use any of his skills, except his first, "Charge", which just restores 30 HP (Well... LF in my game) nothing happens when he travels between those floors, I know because i've checked every, single event in the entire dungeon, and nothing appears to be causing it... Hmm... Quite the conundrum, anyone else think they can help?

Wasn't this the same thing as you asked last time?

Here is my thoughts:

1. You gave the skills a weapon attribute.
If you have a weapon attribute, the skill can only be used when the character have a weapon equiped with the same weapon attribute.
Weapon attributes can be found where you can find all other attributes.
For example, if your "Fire blade" have the attributes Fire and Sword.
The weapon will deal fire and sword damage.
BUT the character won't be able to use the skill unless he got a weapon with the sword attribute. Fire on the other hand is a magic attribute and not weapon.

2. Maybe the mana cost is too high when you reach that part?
There is a chance that you accidentaly made it cost a procent of his max mp instead of a set number.

Try to post some screenshots or something if none of those help out.
