Hey Carter. For 1.3.3 and all before it, we were hosting the plugin at CodeCanyon…but when we switched over to tri.be we killed the CodeCanyon account and took down any Events Calendar versions that were linked to it. So at this point you’ll have to get the code directly from us…if it was a PRO build. (Old codebases of the free The Events Calendar can be downloaded at WordPress.org).
Which release were you looking for? If you were planning on making the jump to 2.0 at any point, if you were running Events Calendar PRO on the old site it should be 1.3.3 and nothing earlier. I can get you that if you’re interested…email pro /a/ tri.be.
