Game won't launch. Please help!

A few days ago I purchased three packs for my birthday, but didn't install them into my game just yet. After doing so, I tried launching the game and it threw an error up saying:

"Unable to start:
Cannot start because game data is missing or damaged. If you have Mods installed please remove them and try again. If not, please repair or reinstall the game via Origin."

I do have mods that I try to keep updated. I removed them and then tried to launch the game again with success. I just would very much like to play with my mods and never had any issues with them before.

I also deleted the broken/conflicted cc and did another scan to make sure no viruses were present as well as any other broken cc I may have missed during the cc purge. None was found. I also updated my drives and did a repair (or two) on the game just in case. I tried to cover all my bases on what the problem may be.

I put the mods folder back where it was and launched the game again to no avail. I don't know what the culprit is on why all of a sudden my game won't launch properly. I don't know if it's the latest update, not installing the packs I purchased that is conflicting with the update, or what.

If anyone has any ideas on what the issue is and how to fix it properly, please let me know. I would greatly appreciate it!

Thank you so much in advance!!
