Hi @rpcosmo, when I try to open your project it takes forever to load and the page becomes extremely unresponsive - even Google Chrome alerts that the site is unresponsive and it completely freezes on the scr\_principal blocks… On that particular screen there is also an error but I cannot try to get rid of that because it completely freezes… ![53](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/6/d/6dea902dc56dc133d63675a1891d9794fda981b2.png) However I managed to install your app anyways by changing the App Package name. I had to replace the last segment. There are some rules for application IDs: > - It must have at least two segments (one or more dots). > - Each segment must start with a letter. > - All characters must be alphanumeric or an underscore [a-zA-Z0-9\_]. @domhnallohanlon this might be something Thunkable should implement since the package name was automatically generated by the system when I remixed it (`com.gmail.christiancraik.6118tool`) @rpcosmo besides the above: do you really need dozens of screens? I think your app is a little too blown up 😬 You might want to take a look at [Domhnalls guide](http://community.thunkable.com/t/a-is-for-alert/272647) Best, Chris --- _[View the full topic](https://community.thunkable.com/t/solved-there-was-a-problem-parsing-the-package/52693)._
