Nobody can tell you anything without proper system info or other technical details like what exact version of AE, comp settings, footage used, effects etc.. You have written a lot, but not provided much useful information.
Addition to Problem 1:
Okay, I allowed all the following processes/programs in my firewall:
- Adobe QT32 Server.exe
I also tried starting AE as adminstrator & using the best processor (NVIDIA High Performing Processor).
Nothing worked. AE still needs about 5 minutes to start hanging all the time on "Initializing MediaCore".
@Mylenium: Sorry, I forgot:
- Adobe Master Collection Version 5.5
- Operation system: Windows 10 (64bit)
- RAM: 8GB
- Intel Core i7
- CPU 2.40GHz
- Graphic Card: NVIDIA GeForce GT650M
I'm a beginner at AE so I cannot exactly explain you the right setting but I try:
- I use an 'Audio Spectrum' to a MP3 which is lasts 1 hour
- Further effects: Some fade ins and fade outs using opacity animation for textes in the video
EDIT: I tried a Re-establishment of Windows to a few days ago. Unfortunately AE already was installed at that date so no effect on the problems - same as before. I also tried starting After Effects in Windows Safe Mode but AE didn't even start! There showed up an error massage which said "After Effects Error: The program crashed when calling up the Plug-In "AEDynamicLinkServer"."
Nobody an idea?
Sorry no, my English is very bad. I'm confused, I think I misunderstood your question and I confused with another question posed on the forum on RAM Preview.
For this problem, here the screencast that shows the RAM Preview problem but now everything returns to normal.
Adobe Creative Cloud (on i7-4750HQ CPU @ 2.00GHz,NVIDIA GeForce GTX 950M 2 GoRAM and Win10 Fam v1607)
After this test, I made several attempts to reproduce the problem but now all operating normally!...very mysterious!
Do you have AVG antivirus installed? If so, let us know; there's a known problem with AVG.
If you don't have AVG, try this: http://helpx.adobe.com/x-productkb/multi/startup-screen-hangs-premiere-after .html
Also, keep in mind that CS 5.5 is very old in computer years and is not officially supported on Windows 10.
