MS Word Crashing upon opening certain files

Hello,

I haven't been having this problem until now but Word "has stopped working" when I try to open some files.  I can't pinpoint which type of files.

Here is the event viewer log:

Faulting application name: WINWORD.EXE, version: 15.0.4787.1000, time stamp: 0x5666b177
Faulting module name: amdocl.dll, version: 10.0.1912.5, time stamp: 0x5661cdfe
Exception code: 0xc0000005
Fault offset: 0x0023506b
Faulting process id: 0x11e4
Faulting application start time: 0x01d15d4b58f5f292
Faulting application path: C:\Program Files\Microsoft Office 15\root\office15\WINWORD.EXE
Faulting module path: C:\WINDOWS\SYSTEM32\amdocl.dll
Report Id: 991cd4ce-c93e-11e5-9c01-9457a5dcb8ec
Faulting package full name: 
Faulting package-relative application ID: 

I tried looking for amdocl.dll but I do not have that file in that location.

Thanks.
