Mail reçu ce jour de TomTom

Confirme le problème de downloadage que j'ai rencontré pour installer la mise à jour trimestrielle de ma carte :
Dear Lionel,
Some of our customers recently experienced a problem when installing the map of Western & Central Europe.
If you have tried to install this map within the last three days and encountered the error message ‘Item was not valid after installation’, follow these steps:
1. Connect your device to your computer and launch TomTom HOME.
2. Log in to your TomTom account. Click Remove items.
3. Select the Items on computer tab, click Maps and tick the box by the map you are trying to install.
4. Click Remove selected items.
5. Click Update my device to download and install the map again.
We apologise for any inconvenience this may have caused.
Kind regards,
The TomTom TeamJ'ai en effet supprimé toute trace de la première installation quelques jours plus tard et j'ai relancé via TomTomHome l'install (qui a alors réussi)...
