TML breaks most other plugins

Hi Guys
I do have a TML license, ,expired, but am about to renew. However it tends to break several plugins whenever I require users to login to see a post. (Example)

[tml-require-user]

(Content goes here)

[else]
You need to be logged in to see this animal..
[theme-my-login]
[/tml-require-user]

Whatever content I put in where is says “Content goes here”, if I put a shortcode in there to run another plugin, TML breaks it, and it won’t work. I am using Image Hopper via Gravityforms to upload photo galleries. (Works perfectly without TML, so there is no problem there). But whenever I use your code to force logins, it breaks most plugins inside the content area. Can you assist? Is there a workaround? Happy to renew both my licences if this can be resolved.
