DS SP2 64 crashing and DS Premium Trial

Hi, i'm currently using DS Pro SP2 64 on Windows 10. I come with 2 matters:

1.- I updated to new SP2 version, and now is crashing everytime. Any hint ?

2.- I'd like to check the 3D capabilities of Premium version. I tried 2 times to download and to install it. Once installed, the only version running still being Professional one, no trace of Premium one. Any hint ?

Thanks in advance
