iPart members cannot find reference part

[Ross33]

I've created a folded sheet metal component, and subsequently created an ipart factory with members that have some folds suppressed (basically to have parts in different stages of the forming process).

The parts and their corresponding .idws were updloaded to vault.

All was well.

I'd updated the components and drawing several times.

Yet this time I have found that the 'original' part (the base part that the ipart factory was created from) has a table that cannot be expanded to show the ipart iterations.

I'm not sure whether someone else has checked it out and broken the link or what, but I am in a bit of a predicatment here.

Is there a way to re-link the factory parts to reference the original file (or vice versa)? Is there possibly a 'cheats way' to try and re-name files so the members re-reference them?

Any advice will be greatly appreciated.

(And before anyone asks, I'm not able to upload the files.)

Thanks.
