Reboot fixed the issue. 

How exactly did you "import" the file?

Das ist seltsam. An meinem Retina-Macbook geht es: https://dl.dropbox.com/u/296640/launchpad_retina.jpg

Eventuell hilft ein Neustart?

You need to copy the tmbundle folder into the #Textastic folder.

Can you please send me an example file to support@textasticapp.com?

Textastic uses the Discount Markdown library. It's certainly possible that it has bugs.

It's great to hear that it's working for you now. Since I saw port 990 in the log, I thought you were already using FTPES. 

I've found the error from your log on this website: http://blog.techstacks.com/2010/03/3-common-causes-of-unknown-ssl-protocol-errors-with-curl.html

Some ISP's and DNS providers like to intercept your failed DNS queries in order to redirect you to a search engine results-style page offering you alternative URLs or "Did you mean...?" counter-query results. If you see an error like this: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol, it could be due to you typing the hostname incorrectly or the hostname is not yet tabled in your DNS. You can verify that with a simple "host" or "nslookup".

Could this be the problem in your case?

Did you try to use FTPS (FTP over SSL) on port 21 instead?

You could also try to select a different "SSL Mode" setting. Maybe the server only encrypts the control channel and not the data channel.

Well, it's great to have such detailed feedback as yours. It's always good to know how other people are using the software. Thanks for that!

Swiping left and right on the text currently moves the cursor, but just one character/word at a time: http://www.textasticapp.com/iphone/manual/lessons/How_can_I_move_the_cursor_using_swipe_gestures.html

But changing that behavior could work.
