Shipping method glitching

This is what i do:

Shipping method 1:
FREE, maximum price = €15,-

Shipping method 2:
€4,- cost, no minimum or maximum price (i've tried putting in 15 min. and 60 max, if i put up min. 15 it doesn't show up below that)

Shipping method 3:
FREE, minimum price €60,-

This is what happens:

The first method always shows up,
The second method always shows up.
the third method doesn't show up at all.

I've been getting way to many glitches with Hikashop,
I'l be loosing customers this way.

When i put it like this:

Method 1: 1-60 euro (4 euro cost)
Method 2: 60-99999 euro (free shipping)

It will give me an 324 error when i go above 60

If i only put up free shipping up to 15 euro, it always shows up.

When i put the only shipping method as:
15-60 euro the page will always crash.

Thanks Nicolas,

I was getting really frustrated there,
everything is working now

PS: i had problems with the contact form, i made a page for it but it wouldn't send a message at all.
i would see an empty box with ok and cancel in the top,
below that:
