Need help decrypt SJEN file!!!

[Maximus64]

Anyone know how do decrypt an "SJEN" file?

As I can see in the MagicJack.exe file I can see 4 call: DecodeBase64, EncodeBase64, DecryptRC4, EncryptRC4

I thinking they encrypt those file with Base64 and RC4



Here is some file that i rip form a bug report to test on:
