I haven't run into this situation, but perhaps re-linking the files could work-- change the name of the .ipt file, open the .idw which, I hope, will ask where the .ipt is, link to the renamed file and see if that does the job. Then close it, change the .ipt back to the original name and re-link again. Does that do anything?
If possible, post the files here (zipped), maybe someone else can get them reconnected.
