I posted this over on the mozillaZine Firefox Builds forum, but haven’t got much help there. Last night I tried several times to update my Minefield from an older build:

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a2pre) Gecko/20061224 Minefield/3.0a2pre ID:2006122404 [cairo]

But either I would get an error message similar to this one or else the update would just fail. Now I was able to update last night after four or five attempts to the latest nightly. This morning for the heck of it I tried and updated once again (on the first attempt) to the newest build:

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a2pre) Gecko/20061231 Minefield/3.0a2pre ID:2006123104 [cairo]

However as soon as I exited Minefield I got the error message again. So I am posting this here to see if anyone else who is using the Minefield Nightly builds can shed some light on this.Some one the forum suggested trying a new profile. I haven’t yet but wondering if the install of Minefield is corrupt. Further, I am having no problems though updating my Bon Echo to the current nightly build:

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.2pre) Gecko/20061231 BonEcho/2.0.0.2pre ID:2006123103
