Preview is not working
Hello, I just got AE today but can’t use it at all because preview does not work. I don’t have this issue with Premiere.
Here is what I have :

When I press the space button, nothing happens excepts that the points around the preview screen disappear. I can move the the blue vertical line along the timeline but it just does not show anything. Also when I quit AE, AE stops answering and I must force the program to shut.
Here are the characteristics of my computer (honestly I don’t really understand what these things are, please tell me if you need more details) :
Intel(R) Core(™) i7-6500U CPU @ 2.50GHz
RAM memory : 8.00Go
Type of system : 64 bits, processor x64
Graphic cards are :
- Inter(R) HD Graphics 520
- NVIDIA GeForce GTX 950M
I’ve already tried a lot of things :
- purging memory and cache disk
- cleaning cache
- using adobe cleaner tool
- cap locks is not switched on
- I’ve tried re-installing it
- Switching audio hardware parameters from MME to ASIO (but I cannot choose ASIO on my computer)
- renaming the adobe after effect file with a .old at the end
Please tell me if you need any more detail
Thank you very much for your help
