Ghost Recon (1) does not start! (no error msg)

[-={Serenity}=-]

hi, i installed ghost recon and it worked really fine. but now it doesnt start anymore and gives me no hint why... no error msg or something. the mouse cursor changes (as if loading) than nothing...
any ideas?

(this happened after i installed graw2, maybe there is a connection?)

thx...

Try restarting your computer, I had this issue once. Restarting my PC helped me.
