# UpNote にアクセスできない場合
UpNote にサインインできない場合、またはアプリ起動時に読み込み画面のまま進まない場合は、以下の手順をお試しください。
1. アプリを最新バージョンに更新します：
* [Windows - Microsoft Store](https://www.microsoft.com/en-us/p/upnote/9mv7690m8f5n?activetab=pivot:overviewtab)
* [Windows - インストーラー](https://download.getupnote.com/app/UpNote%20Setup.exe)
* [Mac](https://itunes.apple.com/us/app/upnote-an-elegant-note-app/id1398373917?ls=1\&mt=12)
2. **Ctrl + Q**（Mac の場合は **Cmd + Q**）で UpNote を完全に終了します。
3. 使用しているプラットフォームに応じて、UpNote のデータフォルダーを削除します：
* **Windows:**
`C:\Users\{your_username}\AppData\Roaming\UpNote`\

`~/Library/Containers/com.getupnote.desktop/Data/Library/Application Support/UpNote/`\
見つからない場合は、ターミナルで以下のコマンドを実行してください：

* **Linux:**
`$HOME/.config/UpNote`
4. UpNote を再起動し、再度アカウントでサインインしてください。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://help.getupnote.com/ja/resources/troubleshoot-issues/unable-to-access-upnote.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
