Sorry you are having problems with it. I have not heard of anyone else having issues opening it. I posted it on another site and they seemed to be able to open it.
There is Darby;s Tropicals on I35 in New Braunfels just outside of SA. Nice selection and great staff. Closed Sunday and Monday.
Also, we are having a meeting on Sunday October 13th if your around. Greg Steeves will be doing a presentation on the Comal River. If your on Facebook, you can join our FB group We have quite a few people from outside the SA area. https://www.facebook.com/groups/SAAPC/
