All this is strange I've got CB 1.1 and fireboard always running fine (except that the integration is not very good for now, but at least no huge problems like you have).
Sorry I may not have read the whole thread since the beginning but did you choose integration of CB in the backend and first of all before clicked on the "click here" link to update database to prepare it to support cb before you activated the integration?
Do you have any special plugin associated to your CB installation?
good luck
PS:=> although this thread says it is due to CB integration, did you try without integration and did you have the same problems or was it fine when not integrated? and are you using the default template?
