Ram preview only 2 seconds

Hi community. 
I have an a problem with my AE previwes.

Not matter how the complex is the composition it only shoes only 2 seconds in a preview. I've tried setting up all the memory again, adjusting the resolutuion to third, deleting cache, re istalling AE, and have the same issue. 

Now I've update the las version and no fix at all. 

In AE Beta works well. But not in 24.6.9

Can you help me??
