If you have a problem with any Magix software, the first "place to ask" is here! We are all fellow-users but a considerable number of us have quite extensive working knowledge of at least some of the products so can at least make suggestions of how problems might be resolved.
From your post title I assume you are having a problem updating your software. Which software and what problems?
If we are not able to help you will need to use the Support System to raise a ticket. There is no Contact Us option any longer.
First, I assume from what you write that any update does not install. Is that correct? Under Help>About, exactly which version build do you currently have? Is your Update Service still current, i.e. is it less than 12 months since you bought the product or any upgrade?
The loss of the toolbar, is that as a direct result of attempting the update? Pressing F9, the shortcut to reset the window arrangement, should correct any such error. Does it work for you? If not, what happens when you press that key?
Again, the more specific information you can give us, e.g. a step by step process which always fails ("I do x and then I do y and the result is z") will be very helpful.
I have version 184.108.40.206 (UDP3) UG Code 8445Ka1. It tells me that there is an update available to go to version 19.02.58. So when I choose the option to update (and have done this several times probably 5 or 6 times) when I log back into the program I have lost the upper tool bar. This stops me from closing the program properly etc and go into the File and Edit options etc. At the time of trying I was still within my update contract but I feel that if the updates are wrong I am not sure I want to pay some more money for the extra 12 month (I am prepared to do so though) The F9 function you suggest does not do anything ! The first time I did the update was on the 31st December 2020. In the end I reinstalled the program and got my tool bar back.
and delete the videodeluxe.ini file, then start Movie Edit Pro - note this will reset any custom folder paths you have created.
Note if you may see the AppData folder as it is a hidden folder - you may need to turn on the Hidden items option in the View tab to see it, alternatively you can type %appdata% in the Explorer address bar as shown below to open the folder.
