Windows7にてCygwin環境を構築し、Texを利用していたのですが、ある日platexコマンドを打つと

$ platex a.tex
This is e-pTeX, Version 3.14159265-p3.7-160201-2.6 (utf8.euc) (TeX Live 2016/Cygwin) (preloaded format=platex)
restricted \write18 enabled.
---! /var/lib/texmf/web2c/eptex/platex.fmt doesn't match eptex.pool
(Fatal format file error; I'm stymied)

上記のように出てくるようになってしまいました。
色々と検索をかけて直す方法を調べたのですが、直すことができません。
どうすれば再び正常に動くようになるのでしょうか？

fmtutilコマンドを使用した結果は以下の様に出てきます。ただ、直りはしません。

$ fmtutil -byfmt platex
