It is not clear what pangaga is trying to save.
One possibility is :
"I do not expect any difficulties with this task", which means "I do not think I shall encounter any problems."
We rarely, if ever, use "I have no difficulties..." as a statement. I can't think of a situation where we might use it. I suppose if asked, "Do you have any financial difficulties?", we might give "I don't have difficulties" as an elliptical defiant answer.
Another possibility is:
"I had no difficulty in completing this task."
Another possibility is:
"I don't have a problem with doing this on my own", which means "I am willing to do it without help from others."
Well, we don't know what pangaga wishes to say.
