FBAR, w/ no income, I can"t e-file. Is there a better way?

I am a US citizen, have no income in the States, but I do receive a very small amount of interest from my foreign account. TTax says i can not file electronically this year. Is this because i have no income?  Do i really have to pay TTax for such a basic filing, especially if i have to do the FBAR on my own anyhow?
