The complete error message reads, "Failed to decompress file. Please use the "CIG Game Launcher -> Settings -> Analyze Game Files -> Verify" option to verify the content of the Data.p4k file." I've verified it several times and it never finds an error or re-downloads the file. I thought it could be an issue with my SSD, so I renamed "Data.p4k" to "Data.p4k.old" and launched the client to have it re-download the file. This way, it writes the data to a physically different location on the drive. Since the file has been re-downloaded, I'm seeing this error less, but I'm still seeing it. I'm also curious about the file size. Can someone tell me what the correct file size is please? My old version and new version are different sizes. The old version is previous patch though. The new one is 3.5.0-LIVE.1473310. What's the current file size of Data.p4k please? Any suggestions?
