Did you activated the new license? It doesn't get activated automatically just by the fact of purchase. Also please note, that license must be activated only after installing SB and CodeMeter user runtime(comes with SB installer); here is a tutorial video with walk-through:
It is hard to say what exactly went wrong in your case, and I'd prefer not to make guesses here. Still you need to address the situation somehow and I'll suggest to check if maps folder from your previous installation is still somewhere else on your computer(e.g. on other drive, for example), unless you always utilized default location C:\ProgramData\eSim Games\Steel Beasts\maps.
If there is an old folder found somewhere, you can define it as a new file path for maps:
1) Make sure that it contains 'Default' map package; if not- copy-paste it there, since SB would not run without it.
2) Launch SB as administrator (right click on shortcut> More...>Run as Administrator)
3) In the Main Menu pick 'Options', then 'File paths' and check what address is listed there; probably it would be C:\ProgramData\eSim Games\Steel Beasts\maps
4) Change location of map package folder by left-clicking 'Map Package Folder' line- dialog will pop-up, navigate to required folder and confirm your selection by clicking 'Select' button
If there no such old folder found for whatever reason, I'll suggest to re-install everything starting with SB Maps first, then SB Pro PE itself, and Map tools as a final touch. Running maps installer when everything else is already done was causing issues to some people in the past, so complete re-installation is a very time-consumable, but probably a safer option.
P.S.
It is also worth to keep in mind, that optional Legacy Maps Installer places pre-4.1 maps only to C:\ProgramData\eSim Games\Steel Beasts\maps.
Please contact sales@esimgames.com; it is possible to replace broken CodeMeter stick (for a fee). Also it makes sense to run CmDust diagnostic utility and attach resulting log file to your email to sales, but please DO NOT post this log here, since it contain sensitive data.
Hello. If you have a Classic License, then it would not be affected by re-installation of Windows, since license is stored on USB key and is not bound to your computer's hardware or operating system copy. After re-installing Windows you would need to install SB Pro PE and a CodeMeter runtime (it is is included to SB installer anyway).
