It looks like your array is not 10 elements long (is it 5 elements?).
When you change MaxLength, you are trying to look at elements that don't exist in or all of:

enemy[]
enemyX#[]
enemyY#[]

When you dimension the array you're giving it 10 elements
The first element in the array is 0 last will be 9
If you change the for loop to
For c = 0 to MaxEnemy - 1

It should work

There's a bit of an anomaly in arrays. If you

global dim enemy[5]

You get array elements 0 to 5 (6 elements)
So you don't need to use

For c = 0 to MaxEnemy - 1

like you might in other languages.

When you change MaxEnemy to 10, you also need to change the array length to 10. The array has no connection to the variable MaxEnemy once you have declared the array length. Here is your original code with an amendment (compatible with AppGameKit V1 or V2):
