Nokia :: E72 - Deleted All Messages / Backup Wont Restore Texts On My Folders?

Basically on E72, I had messages in inbox, my folders and sent section. Once I restarted phone and then phone froze. I felt the problem was due to Vlingo application, because I pressed home button to see which applications were open that were casuing the freezing. So I restarted the phone and all messages were deleted. However my messages were saved as a backup on another memory card. So I only lost a couple of texts. But the same, exactly same problem happened yesterday. Now all texts on both memory cards have been deleted. I have now disabled vlingo to open on start up.

1. The only backup I have now is a pc suite backup of texts, as an .nbu file which I can restore using pc suite or ovi suite. However after I restore, the messaging application does not open and I have to restart phone. Also the texts inside "my folder" do not appear, only in my inbox and sent. Is there any way, of getting all the texts to appear including my folder texts?

2. Obviously the above solution doesnt give me all my texts back, so is there any chance of restoring the texts, from the memory cards even though it doesnt work when I insert it inside the E72. Im hoping by restoring old data inside the memory card by opening it on the laptop or something?

3. I heard, that texts do not get deleted at all, but just blocked, so anyone know if I can unblock them?

4. Or can my network provider send me texts, that I have recieved and sent over last couple of months.
