Created Unassigned: CalCheck Crashes during Start [891]

Hi there, trying to run the CalCheck tool to look at some sync issues with an iOS device, however when I try to run the application on the users machine it always crashes after prompting for which profile to use. Application log shows the following.

```
Faulting application name: CalCheck.exe, version: 2.0.0.0, time stamp: 0x506f322b
Faulting module name: CalCheck.exe, version: 2.0.0.0, time stamp: 0x506f322b
Exception code: 0xc0000005
Fault offset: 0x0000c906
Faulting process id: 0x18f4
Faulting application start time: 0x01ceb631d16885df
Faulting application path: C:\CalCheck_x86\CalCheck.exe
Faulting module path: C:\CalCheck_x86\CalCheck.exe
Report Id: 10fafe86-2225-11e3-b01a-506313ca669d

```

Any idea on what would be the issue causing it to crash?

Thanks
