My After Effects rendering issue, i've tried so many things to fix it.

So, i am trying to render my After Effects project, but every time i try to render it just gives me the sheep sound. Sometimes it tells me why, sometimes it doesn't, but the time it did tell me was this:

the file 'Users/(my name)/Library/Caches/Adobe/After Effects/17.0/Disk Cache - (my name).noindex/08

/08e6539c-9f38-4eb7-0346-43cc3d0f560f.ADBELCV.B483623.AAAAAPD---9JBAAAOAQAAAAAAADw----SQQAADgEAAAAAAA8P---0kEAAA4BAAAAAAAAAPD---9JBAAAOAQAAAAAAAA=.aecache' could not be found.

i use a:

MacBook Pro (Retina, 13-inch, Early 2015)

Processor 2.9 GHz Dual-Core Intel Core i5

Memory 16 GB 1867 MHz DDR3

Startup Disk Macintosh HD

Graphics Intel Iris Graphics 6100 1536 MB

Another error, was this:

Since then i've been rendering with Mercury Software Only.

My Project is 31s long.

Thanks,

Ellie
