I am using Wowza3.0.3 on windows7. The server boots up normally and it correctly prints my licence number in the beginning 2011-11-16 17:04:18 EET comment server INFO 200 - Server License Key: SVRB3-XXXXX-XXXXX-XXXXX-XXXXX-vBf44 However when i try to start a stream i get 2011-11-16 17:05:46 EET comment server INFO 200 - MediaStreamMap.addLicense[new]: java.lang.NumberFormatException: For input string: "8ݢ - - - 87.82 - - - - - - - - - - - - - - - - - - - - - - - - - 2011-11-16 17:05:46 EET comment server WARN 200 - Licensing[vms/_definst_/3-Camera3.vmsx]: \*\*\* Hit license limit for publishing streams. Publishing stream is stopped. \*\*\* - - - 87.821 - I have rechecked the licence file, I have only a single developer licence. The licence number is printed in the first line and there is also a new line at the end. I removed the newline and retried with the same result. What could be the problem? Thanks Özgür ---

Özgür, It’s a license limitation of the developer license. Richard ---

Ozgur, It is 1 stream in and up to 9 out in the developer edition [https://www.wowza.com/developer.html](https://www.wowza.com/developer.html) Richard ---

Maybe it is not plain text? If you haven’t got this, zip up conf and logs and send them to support@wowza.com with a link to this thread for reference Richard ---

Richard, Do you mean that i cant even start a single live stream with the developer license? I thought the limit was 10 live streams. Ozgur ---

Dear Richard, This is not a developer license issue. In our company we also have monthly subscriber license. I tried with that license and the result is the same. I was expecting this since in my previous post i have sent the error "MediaStreamMap.addLicense[new]: java.lang.NumberFormatException: For input string: “8ݢ - - - 87.82” This seems to indicate that somehow wowza is not able to read the license file. Someone suggested that this might be a 64 bit JVM issue. I have a 64 bit JVM. Developers in our company who have 32 bit JVM are not running into this problem. Regards, Özgür ---

Unfortunately switching to 32 bit JVM or changing the file encoding to UTF-8 did not work. I still get the MediaStreamMap.addLicense[new]: java.lang.NumberFormatException: For input string: “B7Ä°1H” error. This really looks like an encoding problem. But I am out of ideas. Please Help. Özgür ---

Hi Özgür, That’s a good tip about the 32-bit. I have a feeling it’s a file encoding issue with your server.license file. I see that the input string is about half the number of bytes as the Wowza license. Possibly, you’re using UTF-16 instead of the default UTF-8 (in debian). Check your locale, and ensure that you’re using the same file encoding as the working systems.
