Issues occurred following an update of the plugin

Hi,

I updated the plugin today and it seems to have resulted in a broken form.

The first issue was that the tabs in my forms had lost their labels but it didn't take long to reapply those.

The second issue was that when I updated the longer form I seemed to get a problem that may have caused a corrupted save. This may or may not be related to the update as the other forms are OK now I've fixed the tab labels.

I tried to use Pastebin to show the code but the lines from the exported form for post_content and post_excerpt failed to show when I copied it over there which further makes me think there's a corruption in the save.

I've exported the broken form and then imported it again and I get a report saying that it doesn't contain any fields which is why I think it's corrupted in the save.

This form has hundreds of fields so I really don't want to have to try and rebuild it from scratch.

Is there a good way to check the file and fix it if there's corruption?

Thanks.
