[BioC] SRAdb error

[Ayten YIGITER]

Hi, I am trying to get the SRAdb package work. I have successfully installed the SRAdb package and then I have got the following error: 
 
 
library(SRAdb)
sqlfile <- getSRAdbFile()
URL 'http://watson.nci.nih.gov/~zhujack/SRAmetadb.sqlite.gz' deneniyor
Content type 'application/octet-stream' length 187043912 bytes (178.4 Mb)

Unzipping... 
Error: sqliteNewConnection(drv, ...) : 
RS-DBI driver: (could not connect to dbname:
unable to open database file"

 
Could you help me at this point?

Sincerely yours
