Hello E A Johnson,
Welcome to the Community page,
Here is how to fix it,
- open the folder that contains your company file.
- Find the files with the same file name as your company files but with extentsions.ND and .TLG.
company_file.qbw.nd
company_file.qbw.tlg
3.Right-click each file and select Rename. Add the word OLD at the end of each file name. Ex: company_file.qbw.nd.OLD
4.Open QuickBooks again and try to sign in to your company file. If the same issue occurs, proceed to solution 2.
