Imacros comments after websta upgrade

So the script I was using for automating IG comments via websta stopped working after their recent update.
It fills in the form with the comment but fails to click the submit button. Any help appreciated
This is the script:
SET !ERRORIGNORE YES
REFRESH
TAG POS=1 TYPE=TEXTAREA FORM=ACTION:/api/comments ATTR=CLASS:"form-control" CONTENT=Nice
TAG POS=1 TYPE=INPUT:SUBMIT FORM=ACTION:/api/comments ATTR=NAME:submit
WAIT SECONDS=81

Man I have not used good old iMacros in a long time. Did they ever add XPath Support? if so you can try this

since the api is down i don't see a big chance to make this running again.
