change one drive password

HELPPPPP!

I have been running my dashboard successfully for a couple of months.

Data model created onsite in excel.  Uploaded to One Drive as my source file.  This morning I changed my One Drive password (couldnt remember it so had to reset).  Now I am getting an error

"It appears that your OneDrive - Personal password has changed or expired.  To fix this issue, delete the dataset (which will also delete your reports) and re-import the file."

I have 28 reports, and 28 associated dashboards.  Simply deleting them and starting again really isnt an option and seems ridiculous?  How can I change the password setting for the original file?  I tried to go back into OneDrive and change the password back to an old one (found it!) and it wont let me as you cant use a previous password.

HELP!
