(VCL) I get " Unit ... was compiled with a different version of ..." error.
The error is caused by the conflict between different versions of SecureBlackbox units, which you probably installed in different moments of time.
The solution is:
1) Use Uninstall SecureBlackbox command from Start Menu -> Programs -> EldoS -> SecureBlackbox to uninstall SecureBlackbox.
2) Perform a search for all files that match the following masks: "SB*.*", "*BBox*.*" on all your hard drives.
3) Remove all the found files (some entries with BPL extension will be found in %SYSTEMROOT%\System32 directory).
4) Delete the folder to which you installed SecureBlackbox.
5) Install SecureBlackbox again.
This should solve the problem.
