Calibre Python error on Win10

Hi everyone, I've a huge problem with the last releases of Calibre (2.61 and 2.62)
I'm using it with Win10 and it doesn't work anymore.
Each time I try to open it, it pops up the following message:

Python function terminated unexpectedly
Failed to load icu with error: MemoryLoadLibrary() failed loading icu.pyd (Error Code: 1)

I already tried to uninstall and install again but it did not work.
I have run out of options!!!

Please :help:
