Strange formatting problem with Crystal Reports

I am using Crystal Reports v10.0.x on Windows Server 2003 SP2. I have an .rpt file that gets exported into a PDF format using the Crystal Reports Engine thingy.

new CrystalDecisions.CrystalReports.Engine.ReportDocument().ExportToDisk(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat, fullExportFileName);

I have this report on two boxes. Both the boxes are Windows Server 2003 with SP 2 running the same version of Crystal Reports. Let's call these boxes box 1 and box 2.

Till now, all reports ran fine on both the boxes. Suddenly, since yesterday, one box 1, all reports have a formatting issue. All reports that have text fields/text boxes with running paragraph text truncate the right most few characters on every line, or at least that is how they display it, if you know what I mean.

For e.g. the text

Today is a great day for everything else
except this problem I am facing with Crystal
Reports. And then, there's a whole lot of
work to do after this. I am ****ing sick
and tired of this job.

is displayed as:

Today is a great day for everything el
except this problem I am facing with Cr
Reports. And then, there's a whole lot o
work to do after this. I am ****ing si
and tired of this job.

The code on both the boxes is the same, and the .rpt files, too, are the same. Please help.
