Troubleshooting

A download fails

Click Failed — see logs on the row: the end of the log gives the reason.
Sites change often: Settings › System › Re-install yt-dlp installs the latest version (Orbit also updates it at every launch).
For YouTube, if the log mentions "JavaScript runtime" or formats are missing: Settings › System, install the JS engine for YouTube (Deno).
Private, members-only or age-restricted content: turn on the Cookie icon of the bar (you must be signed in to the site in Chrome), or open the page in the SNIFFER.
Menu › Downloads › Restart Failed Downloads restarts every failure.

"File deleted" on a finished download

The file was moved or deleted from the disk. Download again gets it back, or remove the row.

Orbit closed during a download

Start Orbit again: downloads resume where they stopped. HandBrake and Topaz queues come back too, but you have to restart them by hand.

An AI tool is slow or runs out of memory

Close games and programs that use the graphics card.
Keep Settings › Downloads › Simultaneous AI jobs (GPU) at 1.
Set a Maximum VRAM for AI to leave some margin.
In AI Enhance, lower the tile size; in AI 3D Creation, pick Fast or fewer Faces.
In Paint a plate, use Stop when you are done: ComfyUI frees the video memory.

"An NVIDIA graphics card is required"

AI 3D Creation, Paint a plate and local AI Generation use CUDA, which only exists on NVIDIA cards. On another PC, AI Generation goes through the online Flux service. The other AI tools (upscale, interpolation, cutout, magic eraser) work with every recent card.

The interface flickers or stays black

Settings › AI & Performance › Disable hardware acceleration, then restart Orbit. If the interface is slow, tone down the Liquid glass (Subtle preset) or turn it off in Settings › Appearance.

A Premium tool stays locked

Check the bottom of the sidebar: it should read Premium active.
After a payment, open the Premium window: it unlocks as soon as the payment is confirmed.
Update required: your version is too old for the AI tools; click the button to install the latest one.

The antivirus blocks Orbit or a module

Orbit downloads engines (yt-dlp, ffmpeg, AI models) into C:\Users\<you>\.orbit. If your antivirus blocks one, add this folder to its exceptions, then reinstall the module from Settings › Modules & AI.

Free up space

Settings › System › Temporary files › Clear deletes the work files.
Settings › Modules & AI: remove the models of tools you do not use (they download again if needed).

Report a problem

Settings › About, bug report: describe what you were doing and what happened, then send the report. The last 25 lines of the log are attached, without your user name. The full log is in Settings › System › View logs.
