If you still have the repos in your repo tab on ArmA3Sync, you can modify them to use the new URL with ease:
Just replace co.uk with eu. May not work for everyone, some have reported receiving errors. I also believe the auto configs are currently incorrectly setup - we are fixing these issues.
Once this is done, click the modsets button on the addons tab, and reimport them. Like so:selecting them in a weird order as above is not necessary
If you do encounter an error, please post an image or copy the error message here.
