Lately a lot of these errors where reported and everyone started a new thread for it. So now here's a sticky for these two errors:
No entry 'bin\config.bin/CfgInGameUI/MPTable.shadow
Error compiling pixel shader PSSpecularAlpha:0
Any other thread that gets created about these two errors are going to be closed without further notice.
Run Steam and ArmA 2 as Admin.
You may have to close down Steam first, then make sure you're running it as Administrator. This should in most cases solve both problems.
Update GPU drivers
Some have reported that the second error (the pixel shader) can be solved by updating the graphic drivers.
nVidia driver download page
ATI/AMD driver download page
Some other threads about the same errors, maybe containing more info and possible solutions if the above didn't helped:
