I have downloaded the newest version of TBM (6.1.78) and attempted to transfer data from the previous version (6.1.66) through a tbmdb.sqlite file.
This worked momentaarily and I the screen opened to the most recent invoice with all of the correct data. However, the toggles on the side bar (for clients, jobs etc) would not open when clicked so I shut the window and restarted it.
I am now met with a blank screen and the following message in the applog:
ERROR Can't start TBM System.NullReferenceException: Object reference not set to an instance of an object.
Is there any help that you could give me?
Thank you in advance
