Export CSV is missing data or contains extra characters

PHP Version: 5.2.10-2ubuntu6.4
MySQL Version: 5.1.37
WordPress Version: 3.1.1
Gravity Forms Version: 1.5.1.1

After updating to Gravity Forms 1.5.0, some odd behaviors have crept in on the Export to CSV functionality. I now have one Form that the export is only a single field '1463', where that is not one of the columns and is not found in the data. The rest is totally empty, where this form should have around 1500 rows.

Another form adds a row before the header row that is just '2063', and then on row 2 begins the normal header row that usually is in row 1. The first field of the header row in this export is 'Product Name' but displays as '"Product Name"'. The rest of the 2000 rows of data seem to display normally.

Updating to 1.5.1.1 has not altered this behavior. The exported CSVs can be e-mailed if necessary.

The CSV export is a vital part of how Gravity Forms is used, so any help is appreciated.

Edit: checked the database, and that field in xxxx_rg_form_meta is listed just as 'Product Name', so it's stored in the DB right, but isn't being read correctly at some point.

It's internal only behind a company VPN, so I can't provide the log in or URL. Any other options? DB backup helpful?

Thank goodness... Granted, I should have done 'Wordpress troubleshooting 101' first... I swear I kick myself every time I don't do that, but I deactivated the only other plugin that was updated recently and now the form that wouldn't export anything at all exports successfully again. All forms still have the extra row with the number and junk characters in the first field but a major phew....

'Better WP Security' is the seemingly incompatible plugin. http://www.chriswiegman.com/projects/better-wp-security/.
