Error: DLL MD5 mismatch, broken installation.

Hi,

I had this strange problem. When I loaded rJava package, I had the "D -- DLL MD5 mismatch, broken installation." message.

I tried: removed the package, exit RStudio, deleted rJava folder left in library, reinstalled again but still encountered the same error message.

Does anyone have this problem before? Thank you!
