What version of Grid2 and game type (classic or retail) are you using ?

Classic (TBC) 2.0.12-bcc

What game client version (windows or mac) and language are you using ?

Windows 10  

What steps will reproduce the problem?

If I press any new rank heal I get a lua error  

Did you try having Grid2 as the only enabled addon and everything else disabled?

Yes

Was it working in a previous version? If yes, which was the last good one?

  I am not sure since this is the first time I have tried a new rank healing spell. 

Do you have an error log of what happened? If you don't see any errors, make sure that error reporting is enabled (`/console scriptErrors 1`) or install [BugSack](https://mods.curse.com/addons/wow/BugSack).

Please provide any additional information below.

Update to latest version 2.0.13-beta-bcc and report back if this version fixes the issue:

I redownloaded the addon manually, and it worked, but when I levelled again it gave me the same error. I don't think it is for the spell but maybe the level of the player?

You have reinstalled version 2.0.12 but you must install version 2.0.13-beta:

https://www.wowace.com/projects/grid2/files/3318824

This version comes with a different libhealcomm4 library.

Anyway if version 2.0.13-beta fails too, i cannot fix this kind of issue, because is caused by an external library, in this case you must fill an issue here:
