i've the same problem that is already resolved here http://gtaforums.com...t-metapso-file/
But for me this solution doesn't work.
I'm using the latest legal GTA5 1.40 (1103) RSC Version and also the latest OpenIV Version.
I'll explain what i want to do and what i did already.
I want to get my Tuning Parts for Addon Cars working, so i've to add the Modkits and the Lights to the carcols.ymt.
So i've exported the carcols.ymt as "META/XML" with OpenIV, then i've added my Modkits and Lights with Notepad++ and checked it for Syntax Errors with the XML Tools Plugin, it says "No error detected".
So the carcols.ymt.xml should be fine, but when i try to import it as "OpenFormats", i get the "carcols.ymt.xml(Line 0): Unable to import META/PSO file." Message...
So whats wrong here, where is the problem?
I hope someone can help me with this please.
Thanks in advance
