Help to crack program (idk anything about it lol tried with ai help but nothing)

🔹 Program Name & Version:
ETS2/ATS Lighting Mod v2.0.17.3 (snowymoon.io)

🔹 Protection Analysis (DIE, PEiD, ProtectionID results):

• DIE: Microsoft Visual C++ 2019, 64-bit, GUI

• ProtectionID: Custom license key check (Patreon-based activation)

• IDA Analysis: License validation via function sub_1802168E0 comparing with magic value 0x13EC. Conditional jump jnz used for failure.

🔹 Any Extra Protections:

• No disk wiper, BSOD, or VM detection detected.

• Protection is primarily a license key check with Patreon integration.

• Note: The mod connects to snowymoon.io for validation? (Not fully analyzed for network calls).

🔹 What Does the Program Do?:
Lighting mod for Euro Truck Simulator 2 and American Truck Simulator. Enhances graphics, headlights, and environmental lighting.

🔹 Supported Systems & Architectures:
Windows 10-11 x64 only (64-bit executable).

🔹 Limitations:

• Full functionality locked without valid Patreon license key.

• Displays "Invalid license" if key is not provided or incorrect.

🔹 Download Link (Preferably original or clean source):
https://cdn2.snowymoon.io/lighting_v2/ets2ats_lighting_v2_0_17_3_snowymoon.io.zip

🔹 Additional Notes:

• Already attempted patching the main jnz check in sub_1800703E0 (replaced with NOPs), but still getting "invalid license".

• Suspected additional checks elsewhere. Need help to fully bypass license validation.

• Goal: To crack it and make it work for free.
