I cant work out where OSA.dll is in my mod list.

[SunsterSKSE]

Hi guys I have been itching to get back into Skyrim so I just updated my current mods and I am having some issues, 

 

1. I get a crash when I try to launch the game from the menu, I have posted my crash log here:  https://pastebin.com/n53jaVQy

 

2. I keep getting this error message: OSA.dll: disabled, only compatible with earlier versions that 1.6.629. 

I feel I have gone through my mod list and got rid of any old versions of OSA, OSTIM so I cant workout where this OSA.dll is unless its in the new Ostim Standalone versions?

 

I cant work out these issues so you amazing people wouldn't mind taking a look and point me where I am going wrong?

 

 

Thank you very much in advance!!!!!
