Thesis is a paid WordPress Theme Framework. All of us are volunteers and those who are somewhat related to WordPress codex things (like me, you can get involved too) do not provide any support for any paid theme.
We support only which are free like WordPress itself.
The reason is – you have paid for that help and support for Thesis. Please go to their forum (or whatever the support option is) and ask them.
