# Studio Common Issues

## Studio Groomer's Tool Issue

<details>

<summary><strong>We’re moving to a new Maya version - what should we do?</strong></summary>

Download Groomer's Tool for that Maya version, and put the new xgtc in a separate folder, for example:

```
'D:/.../plugins/2026/xgtc/'
```

Relaunch Maya, update the **xgtcPath** in the launch command, and use the same license/email for validation.

## XGT Refresher Troubleshooting

### Recommended Studio Refresher Schedule

To keep licenses up to date, while letting artists work offline, schedule the **Studio refresher** at these intervals:

* Monthly plans: Twice per week
* Quarterly / Bi-Annually / Yearly plans: Once per week

### Troubleshooting

| Symptom                                         | Likely cause                                                    | Fix                                                                                             |
| ----------------------------------------------- | --------------------------------------------------------------- | ----------------------------------------------------------------------------------------------- |
| `ERROR: bad magic number in 'xgt_license_core'` | Python version mismatch for `.pyc`                              | Refresher machine must have the same matching Python version as the XGT\_Refresher bundle files |
| `verify failed: ...`                            | Network block, wrong product ID, or license key missing in JSON | Allow outbound HTTPS; pass `--product-id`; confirm JSON has `license_key`.                      |
| `Permission denied` writing JSON                | Share not writable from scheduler box                           | Run on an IT/RW box; fix share conditions; avoid read-only mounts.                              |
| Written OK but artists don’t see change         | Artists looking at a different xgtc file/path                   | Ensure everyone points to the intended target path.                                             |
