Popcorn-Time movies error loading data, try again later
Fixed it by clearing the parent directory /Users/SOME_USER/Library/Application Support/Popcorn-Time. (Replace SOME_USER)

I also have to clear all cache and data.

I also got the latest version from the continuous build in http://ci.popcorntime.io/job/Popcorn-Time/

Update: I also use this technique to debug. I run the app in the command line.

$ pwd
/Applications/Popcorn-Time.app/Contents/MacOS
$ ./node-webkit


Noticed this error (replace xxx with the username).

[61835:0207/235212:ERROR:leveldb_database.cc(280)] Failed to open LevelDB database

I deleted /Users/xxx/Library/Application Support/Popcorn-Time/IndexedDB and the issue disappears.
