Rotting roots of vanilla orchid

[Daan]

Hi everyone. 1.5 months ago, I bought two vanilla cuttings. They already had roots. I tried to keep them alive in a warm room inside my house. I live in The Netherlands so outside it was way too cold. I watered it and fertillized it the way I should and I used the right soil for orchids. Today I took another look at them and the leaves looked wrinkled and I just found out that all the roots are dried out/rotten... Is there any way to save them?

Ps. The soil in which I got them was not regular orchid soil, but more some kind of compost which still sticks to the roots.
