Crystal Report+unrecognized escape sequence

Question

Hello,

I use crystalreport in my windows application and while typing the code I got "unrecognized escape sequence"  in the path definition when loading the report. When trying to run I got "Load report failed" error.
The line for loading looks like this:

cryRpt.Load(

and I am sure the path is that.

Can anybody help me please what might be the problem?

Thanks in advance.
