OpenRealty - TransparentRETS Import failing

We are a small/medium real estate company located in Los Angeles, CA. We have an installation of OpenRealty (Professional Version) and the TransparentRETS add-on which usually would import our listings from a local MLS Server. The RETS MLS import functionality was working on our previous server but then had a hardware failure which forced us to move to another server. Now on the new hardware with no changes to the website the imports are no longer functioning. We suspect that this could be as simple as server settings so we are looking for an individual with strong linux system admin skills in addition to experience with OpenRealty and TransparentRETS or MLS databases.
