Hi all, i think ive managed to corrupt one of mercurial repositories, is there anyway to recover the damage? the message i get when attempting to update the repo to my default branch is:

PS C:\wco\projects\ims\code> hg up -C default
abort: data/Trunk/application/models/priority_model.php.i@83dbdfb60981: no match found!

when i run hg verify, i get the following report:

PS C:\wco\projects\ims\code> hg verify

(first damaged changeset appears to be 0)

since the first damaged changeset is 0, this would appear to be pretty terminal. Is there anyway around this?

any help would be appreciated.
