Verb conjugation of "estrenar" in Spanish

The current situation in Libya is really difficult. I tried to get in contact with acquaintances, but all the phones were not working. I'm really concerned about their well-being. I'll try again later.
Was that all? I was sure that I had a lot more mistakes, because I did not know how to express myself properly. Maybe I am a natural born talent. I am just kidding. Let me know if you need something else.
If you are spell checking my letters, that would be great. I would then do the same with your letters. Can you please correct this email too? I thank you in advance for helping my Spanish.
