Hi @Auditry, welcome to the forums. If you'd attach your logs there are better chances someone can look into this. Link: %LocalAppData%\0ad\ E.g.: C:\Users\JohnDoe\AppData\Local\0ad\

Free Software can legally be sold (although I am not stating this is specifically the case of 0 A.D.) See this: https://www.gnu.org/philosophy/selling.en.html The word "Free" in "Free Software" can be misleading due to its ambiguous meaning. GNU and FSF clarify which interpretation should be given to the word "Free". Quoting from https://www.gnu.org/philosophy/free-sw.html.en: [...] think of “free” as in “free speech,” not as in “free beer.” 

@Perzival12soon in R29 there will be https://gitea.wildfiregames.com/0ad/0ad/pulls/8724 with examples, I know it is needed, because @The Undying Nephalim mentioned it many times in his videos about some factions.

So, I just installed the game and every time I boot up the game, I get an error message. The game works fine I just get no sound. I already updated my drivers and tried looking into the issue but can't seem to find anything that helps. I'm also not the most tech savvy so I don't even know where to start on troubleshooting. Any help or advice is appreciated. I included a screenshot of the error message that pops up.

The license states that it is Free software. It legally can’t be sold.
