[TYPO3-shop] Admin code error

[Marko Minic]

Hello everyone!

i still have a problem with admin code on my site (admin code is not visible) and I am really getting crazy because of this. So I think that the solution might be if I upgrade my tt_products. I have remove it from extensions but I could'n use typo3 anymore, so I needed to restore my previous backup. How can I reinstall my tt_product without loosing all data and settings? Also, where can I found and download latest tt_products 2.8.0 source? Maybe it will solve my problem. Please help!!!

Thanks in advance, 
Marko
