I have seen a few complaints from people here not being able to retrieve their contributions from the new iranian.com.
Your only chance is to bombard them with complains on a daily basis, hoping to have access to your and others material.
I have been able to recover some of my things using Google cache, but how long it will last, I don't know. This new IC behavior resembles so far that of the "besaz o beforoush" class of Tehran who did not or could not see the value of the city's old buildings, and were just interested in demolishing the old to build something more marketable.
Same mentality, different times and circumstances.
Something worth comparing is the quality of the site's material before and after 2007. What you have after 2007 comprise mostly of vulgar hate inciting material by a selective few and one-by-one disappearance of objective read-worthy contributors.
