Hi,
so to try and add to the previous posts.
I think you maybe able to gain access via you reseller , they maybe able to add it back in, typically only 4 version back of on subs.
in this case if you only have a copy of the database on the MDB format , you can use the management tool to convert that mdb to mdf format. This tool is found under the table editor.
it will copy the database and create a mdf format in the same location as the source file.
then you would need to move/copy this to you 2018 location( I would rename the original 2018 dB table), with that place on that location you should then be able to open AS and view the drawing styles/processes.
if this is all good you can use this to migrate the from 2018 to say 2019 then onto 2020.
you will need to be careful because I think they changed some of the tables structures between versions. It can be a bit of struggle, but I have done this, with a little bit of editing in the background.
i think someone already said it maybe better to recreate style in the new version.
There is possible no quick fix here.
hope these comment help out.
