Hi hope someone could help me with this error.

I´m trying to load some variables with this code:

this.loadVariables("https://partner.cola.com/sites/laitclients/outlook/widget/datos/training.txt")

but when i publish my movie y get the next error:

Error opening URL 'https://partner.cola.com/sites/laitclients/outlook/widget/datos/training.txt'

Anyone knows why flash render this error? is because the HTTPS protocol? is there an other way to load the variables from this page?
