1. Go into Utilities and Layouts. Look down the list for Invoices. Click on this. Try to amend by going into Design.
If you do not see the template of the design then it is physically missing. The layouts are called LT files and are normally found in the INVOICES directory.
This problem is normally caused by changing the data directory and simply not copying the layouts at the same time.
2. Check the default program for displaying PDF documents. In Windows 10 updates this may be altered to the Edge Browser during an update. Have a look at the TPN Invoicing manual icon on your Desktop. Has this changed? Displaying an 'e' symbol by chance? Reset this to Adobe Reader if this occurs. Look in Control Panel then Default Programs. Also check that Adobe has not defaulted to 'Protected Mode'. Try to display an invoice from the program and see if its blocked.
3. Check that emailing is working by picking an invoice and using Report/Invoicing/CSV data. Does this send?
