Hi.
Thank you for your described case.
The only reason of such behavior that we are aware of is non latin alpha-numeric symbols in the page name. Can you please check if page's name is only latin alpha-numeric symbols?
Otherwise it should be working properly.
Usually this process looks this way:
1) In the 'Project Metadata Components' you should find the page you need in the list and select a checkbox near it, or you can just toggle "Subscribe" button near the "Apex Pages" item and save changes.
2) After that you should pull from Salesforce (please notice that the new page won't be listed on the first screen of the Pull Wizard)
If the page is not downloaded after this two steps - please let us know if you can find that page in the 'Project Metadata Components' window in the 'Apex Pages' subitems.
In the future if you have 'Subscribe' button toggled on in the 'Project Metadata Components' menu for particular metadata type - you will automatically get all new items of that type each time you are pulling from Salesforce.
Please let me know if this helps you.
Thank you,
Kate
