Problem with Add/Renew Subscription

Hello, i have installed amember but i have a major problem with its function, everything else works fine.. just this small issue i am facing : I have enabled option in Shopping Cart:
"Hide 'Add/Renew Subscription' tab (User Menu)
and show 'Shopping Cart' tab instead"

When user registers on website, he sees his Dashboard with top menu saying: Shopping Cart, but below there is text :
"You have no active subscriptions
Please use Add/Renew subscription form to order or renew subscription."

Screenshot: http://prntscr.com/e46vtb


The problem is that if user clicks on "Add/Renew subscription" text-link he gets to error page saying:
"An Error has occurred
An internal error happened in the script, please contact webmaster for details"

BUT if user clicks on menu tab "Shopping Cart" he can see the products and purchase.

I have read a lot (~6 hours) before posting here but unfortunately nothing solves my issue, if someone can point me how i can delete this text from membership dashboard would be very great!

Issue was solved - I just had to look at Translations menu.. there you can edit the text and link.
