Help!!!!!

ma friend told me about esf and i saw him play it
i downloaded 2.0 alpha and installed it but when i run it it says

cannot find the file c:sierra\half-life\esforces../hl.exe(or one of its components).

dunno what 2 do........can u guys plz tell me?and if ur wondering what kind of game i have.... i have half-life counter-strike the retail one.

i see the prob

c:sierra\half-life\esforces../hl.exe

u need to change the \half-life\ to ur cs directory

it should look like
c:sierra\counter-strike\esforces../cs.exe
or where ever u installed cd
