I have a lot of UserForms as *.frm/*frx in a folder. I do not have the forms in a *.xlsm-Workbook, as I only load the necessary Userforms by need into my workbooks.
Importing the files worked for many years.
Now I can’t load a single of my Userforms into any Workbook anymore.

This is the error-Document-Link:

I created a new UserForm in Excel and exported it. This Form can be imported without a problem, but all my old userforms throw the above mentioned error message.

So this seems as all my old Userfroms are broken.

If so, may there is a repair tool/ method for broken UserForms?

Thank you for any help to rescue the Forms!
