Game has detected a mismatch.

Hi all,

Myself and 3 others been trying to play Zero Hour with no issues but we keep getting game has detected a mismatch.

We play roughly 20-30 mins and it pops up with the mismatch.

We are using C&C online, We tried using GameRanger, which was okay apart from having a lot of troops it starts to lag.

But C&C was perfect without the mismatch.

• We tried removing all mods 
• All customs maps
• Custom hotbars
• All updated with GenPatcher
• Latest GenTools
• Network optimizations to help connect with other players enabled.

Any suggestions to fix this?

Having the same issue tonight as well.  First time this has happened.  Game works fine for about 30 minutes, then we get the mismatch error.
