Restoring Calendar in WLM

Hi

I use WLM to access email provided account my ISP and I use the Calendar to record appointments etc.

Today I formatted and reinstalled Vista Home Premium, and WLM but forgot to backup my Calendar entries.

I do have a complete copy of my original install on an offline disk, can someone please tell me which folder Calendar entries are kept in so I can copy the contents into my new install.

Thanks

Daniel

Anyone??
