Well something has changed.
First of all, we cannot guess your ability, experience, or recipe. If you need help you need to provide a recipe.
Are you cooking by time or by feel? You need to cook the choux paste properly. Then when incorporating the eggs you need to make sure they are not cooked. My guess is the choux paste may be cooking the eggs. Of the two technique steps I just mentioned, this is more likely to be the cause of your choux not rising.
