Projects not Opening

Hi,

I have 4 projects, 3 using ue4.15, and one using ue4.14. All of the projects used to open fine, but now the ue4.14 project opens fine, but any of the ue4.15 projects crash out when opened from the launcher and don’t even make it to the initialising window opening, and no log file is generated in …/saved/logs. This was intermittent for about a week but now fails on 100% of the open attempts.

I tried deleting the Intermediate, Build, and Saved directories to create a complete new rebuild, and the project started the first time, then not again with the same as above.

If you can suggest any help, this would be great, as we have a delivery date coming up, and really need to move forward…

Best regards,
Bruce

Just to update… Think I found what the problem is, my graphics card is on its way out (GTX 760) and over the last few days has started crashing…

I reinstalled the ue4 launcher and when opened it came up with a “fix 4.15” on the launch button. After the reinstall and fix the projects opened. Then the gfx card crashed again after about an hour. After restarting the pc and ue4 the projects refused to open again (even clicking the launch engine button). So reckon when the gfx card crashes it must leave an error state in the engine/launcher that refuses launching the engine the next time it starts up…

New graphics card on the way…

Thx
