R devel - Apr 2008 - inquiry - failed to start R-2.7.0 (Window) (PR#11329)

Dear R team,

I am new to R.  Please forgive me if I am using the incorrect format to 
ask or this is not right place to ask.

I have a little problem with R-2.7.0 for Window.  When I started the 
software I repeatedly receive this message:

"Error in file.exist(name) : unsupported conversion in
'filenameToWchar'
as well as the "Fatal error: unable to restore saved data in .R.data" 
(see attached jpg).  

Not quite understand these last error message (I have never done 
anything with R-2.7.0 and there shouldn't be anything to restore, right?).

I  tried several times with repeated installations and reboot of my 
computer but got the same result.   I have repeated installations of 
R-2.6.2. trying to see if there is anything wrong with my installation 
procedure and computer and it works fine with this earlier version.  I 
have no problem with R-2.6.1 and R-2.6.2 using the same computer i.e. 
Microsoft Windows XP, Intel R Pentium (R) 4 CPU 2.80 GHz with 2.81 GHz 
2.00 GB RAM.

I have also tried this: uninstall all R software and delete the R folder 
(created during installation) and then installs R-2.7.0 again, but same 
error message showed up.

I passed this question to a friend who is using R-2.5.1.  He tried to 
install R-2.7.0 but receive the same error message.  And he passed your 
email address.

Your expert advice would be most appreciated. 

Thanks in advance.
