I think the error comes directly from the method exportAction() from Mage_ImportExport_Adminhtml_ExportController class:

public function exportAction()
{
    if ($this->getRequest()->getPost(Mage_ImportExport_Model_Export::FILTER_ELEMENT_GROUP)) {
        try {
            /** @var $model Mage_ImportExport_Model_Export */
            $model = Mage::getModel('importexport/export');
            $model->setData($this->getRequest()->getParams());

            return $this->_prepareDownloadResponse(
                $model->getFileName(),
                $model->export(),
                $model->getContentType()
            );
        } catch (Mage_Core_Exception $e) {
            $this->_getSession()->addError($e->getMessage());
        } catch (Exception $e) {
            Mage::logException($e);
            $this->_getSession()->addError($this->__('No valid data sent'));
        }
    } else {
        $this->_getSession()->addError($this->__('No valid data sent'));
    }
    return $this->_redirect('*/*/index');
}

So, check the var/log/exception.log, maybe you can see more information about the error.
