A new version of the Open CMA for Vita 1.80 has been made to easily fix the errors alot of people have been receiving. (This also fixes the music/video bug!)
You can download the newest version here or alternatively if you already have the other one installed you can replace the psp2-update.xml file with the correct one corresponding to your appropriate region at the bottom here
Tutorial for the new version:
– Extract the archive in your CMA folder (program files/Sony/Content Manager Assistant by default)
– Quit the CMA if it is running on your PC
– Execute “run.bat” (you need to run it in “Admin mode” on windows 7
– That’s it, now the CMA should run without requiring to be connected to the internet
Its recommended that you do use open CMA when the vhbl files come out. Open CMA for those who do not know is the content manager to copy files to the vita and back but without any internet connection unlike the official Sony CMA. It will also not sneak a patch or do a forced firmware update on your device if one comes out and it will not send any data to Sony about whats being copied, edited, transferred or crashes.
