Proper use of Multikey

I have used multikey32 with three programs for over a year and everything was working fine. Today I tried to install a new program for which I have the .reg file and suddenly nothing works. Help !
To be specific I tried the following :
1) added the reg entries then ran install.cmd
2) ran remove. cnd, then install.cmd, then added the reg entries then ran restart.cmd
I'm getting a series of "Found New Hardware" screens and I thought to point the wizard to the multikey.inf directory.
I' getting a message I cannot install this hardware ffor each try, and finally even the programs that worked stopped working.
Please note that i do not know much about all this as a friend was helping me out but he passed on.
Thanks for any help

may be your new application protection is change

Thanks for the sugestion, but why have the old, working ones stopped working ?

may be new driver updated. remove new driver install the old driver.

I've tried reinstalling the drivers, actually I have tried every driver option given to me through the install wizard for safenet drivers and still I get no result. The message I get when trying to run one specific app is first a screen with "Hasp not found" and then a second with "The instruction at "0x004055165" referenced memory at "0x06e23bb0". The memory could not be "read". Click OK to terminate the program. Anybody can decipher this ?

post your dmp or reg file here
