Solve : pdf password cracking?

Answer»

hello,
wanted to ask for an opinion, ive god a pdf file with a password im trying to crack, ive been trying to use Advanced PDF Password Recovery but it could TAKE years,
however i do know the password is of 7 characters, FIRST one is an uppercase char, REST are LOWERCASE (="Xxxxxxx").
i couldnt limit the software search with the info above (which will make 26^7(=total up./low.case english chars^password's length), it can only make it a mix of chars (which is 52(=total up. and low. chars)^7), which will take about 2 years with my cpu (should take about 5 days with the search limit).
is there a way to limit the search ?
is there any other way you would recommend for me to crack the file?

thanks in advance
