Error -123 = Syntax incorrect?

Hiya, New forum member ... old Pt user (16 years..ouch ) enough blibber blabber ... dumb error ..I'm over this upgrade to 7 already. Could not save "session_name" because The filename,directory name,or volume label syntax is incorrect (123). This was recieved after doing a "save session copy in" .. I'm transplanting sessions to another partition ... the partition is FAT32 ... I'm on XP Pro SP2 + PT 7.1cs10 on a MacPro (Dont laugh) anyway, beyond the obvous stuff (yes,volume label isn't funky, the filename i'm saving as is not funky) .. anyone seen this error? ... Respects, PS: I've been running 6.9 with this setup without flaw.

bump ... come on now ... there's like thousands of you weirdos runnin LE, "Lite" ,whatever you call this version .... some insight here people ... Respects,

hi, Doh .... alright ...alright ... seems everyone and their mother has protools now (and yes, my mom has protools) ..no disrespect ... "weirdos" i mean "studio rats" a scene that in the day ...ran the industry by being the only ones to hammer out crap like this ... my apologies *bows* .. the FAT32? .. cripes .. i woldn't assume that ...if anything, i was trying to keep it all plain jane, thinking that NTFS would just throw more(permission,etc.) in the mix (I'm running another partiion of XP that formatted these disks). The partition is 20GB .. well under the 32gb limit. i myself know 8 people that sit on this forum like it's a religion ... who like me , have this on a laptop next to the rig,mixdesk sidecart,etc. .... always refreshing ... just glad it's got graphics now...bbs style blows when your drunk. i appreciate the time ... I'll figure it out ... Respects,
