checkout page in loop

Hello,

we have the following situation. We have setup our site, Woocommerce and everything works fine. When we enable the multicurrency plugin and when we select for example Yen, we see that the checkout page in getting in a loop and conitually refreshes and reloads itself. Euros works fine. When we disable the plugin, the problem is obviously gone.

Did you see this before and what is the solution to solve this?

Please assist.
