Hello, I have a problem with a notebook tryin to revalidate w7 Ultimate. This notebook is a Toshiba pro s500-10Q PSSE0E. This computer were distributed by an university to the students with dual boot (win7 home premium and a local linux distribution). Using aida64 I saw it have slic 2.1 on the bios, the information is in one of the attached files. When I formatted the computer, I used the certificate: TOSCPL00-TOSCPL-2.1.XRM-MS and the OEM serial of toshiba for W7 ULTIMATE and i can validated it, but sometimes the system validation crash and I need to rearm. Today I cannot rearm again because I have used all rearm attemps but I don't want to format again. I don't know where is the error because I don't find any LOHR certificate for toshiba. Can you help me? I have a RW report that I attach here with the Aida64 Screenshot and rearm error: h**p://w*w.mediafire.com/?780qq7qq3r550ic Thanks for your help and, Excuse me for my bad English.
