Mass Effect 2 not launching after downloading Arrival and Shadow Broker DLC

I have the Mass Effect Trilogy (disc version for PC) and I've played through Mass Effect 1 with no major problems.  I imported my ME1 save file with no issues and finished the main missions of Mass Effect 2 also with no problems launching or loading, until I tried to download Arrival and Shadow Broker DLCs.

System details:

Intel Core i5-3470 CPU/ 3.20 GHz / 8 GB RAM

AMD Radeon HD 7700 / 1.0 GB

Windows 7 Professional (64-bit)

DirectX 10.0

Details about problem:

After I finished the suicide mission, I was able to play a few side missions without problems launching Mass Effect 2.  But after I downloaded and installed Arrival and Shadow Broker from the BioWare Social Network site using my Origin/EA account, I was suddenly unable to launch Mass Effect 2 at all.

The first time I got an awc.dll error, and after looking through all the help forums I was unable to find a solution that worked (downloaded Adobe AIR, etc).  I ended up uninstalling both DLCs.  This got rid of the awc.dll error, but now I cannot open Mass Effect 2 at all.

When I try to open ME 2 as Administrator either from the Desktop shortcut, Program Files folder, or Mass Effect 2 Launcher the browser immediately opens Origin and shows a brief "launching" pop-up before it disappears and nothing happens.  I've tried repairing the program from Origin but it comes back with no errors found.  If I start Origin from Program Files as Administrator then try opening Mass Effect 2 I still get the same problem.  This happens when I have cloud save on or off.

When I try trouble-shooting using XP compatibility mode, I get an "ssleay32.dll" error.

I have not modded the game or altered any of the file locations.

Can I please get some help with this?  It's frustrating because I don't want to risk losing my save files by reinstalling ME2, and I didn't have any problems before trying to download Arrival and Shadow Broker.  I paid for both DLCs so I really want to play them, but now I can't even play the main game anymore.

Thanks for the help.
