Hello,
There is no global issue on the 8.0.13, it might be specific to your environnement.
Please send us a mail at support@pvsyst.com with the folloying info:
- did you just upgrade to 8.0.13 or was it working yesterday ?
- Was your machine updated ?
- if you still have an old version, please generate log (with File > export logs) and send them to us. Otherwise just navigate to C:\Users\<YOUR_USER>\AppData\Local\PVsyst\8.0\Admin and zip the whole folder.
Regards,
Laurent
