I’m assuming you’ve already verified your installation via Steam?

Unfortunately it’s very hard to determine what could be causing persistent data corruption errors as it’s a particularly mysterious problem which we’re still in the process of learning about.

We have a list of solutions here which we’ve created based on what’s worked for players in the past: https://support.fatshark.se/hc/en-us/articles/360021425793--PC-How-to-resolve-data-corruption-errors

In most cases, it’s a result of mismatched RAM speeds. That being said, I’ve recently spoken to a player who learnt their issue was a result of an unstable RAM overclock, so that’s something worth considering, and another player with MSI Afterburner had to re-scan their overclocks.

Please let me know if you need any help with the solutions linked above.
