Loop Files Operator runs forever

Hi All,

Trying to use loop file operator on TripAdvisor data from process mentioned here: https://community.rapidminer.com/t5/RapidMiner-Studio-Knowledge-Base/Synonym-Detection-with-Word2Vec/ta-p/43860.

However, even with 5 files in the directory, the process is stuck at loop files operator. Any suggestions on what's wrong?

Thanks!
