Problem logging in any 1IM application



Today we were working as usual in 1IM and we got a problem compiling the database related with a script that we haven't touched for days. After this, now we can not log in in any 1IM application (the connectivity with the database is working and if we put a wrong password we got the typical login error) and we get the following error:


[810099] Assembly could not be loaded from buffer passed down.

Could not load file or assembly '1517568 bytes loaded from VI.DB, Version=7.1.2016.901, Culture=neutral, PublicKeyToken=xxxxxxxxxxxxx' or one of its dependencies. An attempt was made to load a program with an incorrect format.
Bad IL format.


Any recommendation will be appreciated. Thanks,
