Nobody can tell you anything without proper system info or other technical details.
Well I use a 64-bit Asus desktop.
Intel inside core i3. 4G memory.
"After Effects error: Crash in progress. Last logged message was:
<12252> <DynamicLink> <5> C:\Program Files (x86)\ Common Files\dynamiclink\CS6\dynamiclinkmanager.exe"
This is the crash report, if there is more you need to know just contact me.
